Kriesler 11-20 Midget Plum Pudding Restore 

The capacitor has become "incapacitated". That is funny. I have never heard anyone say that obvious thing before! Great.

I had that exact same radio when I was a kid. I used to listen to seriels like "Dad and Dave" "Hop Harrigan" and several others. I hated it if Mum and Dad told me we were going out and I had to miss any episodes. I am 76 next March and the radio bought back many happy memories. Radio to me is much better than TV because one had to use ones imagination. Thanks for the memories.

35:06 David: I don't know how radio's work, I'm just making this up as I go along... 35:13 Me: /sighs

You are the Sherlock Holmes of radio restoration/repair, always interesting to watch.

Thanks for the great restoration video. You are informative and quite easy to understand when speaking about these radios restorations. Thanks for sharing.

It's always fun watching your videos.

I don't know anything about about radios but I find your videos absorbing. Many thanks

Great video! Love the different camera angles and picture in picture.

Thanks David for another fine video. I always find your videos entertaining and educational. Looking forward to more. Have a wonderful holiday and see you again next year.

Thanks for this! I know very little about radios but watching these is fascinating and hypnotic. Merry Xmas!

Good to see another video, 👍it came out great. Happy New Year to you and yours.

Thanks for your videos David. You've certainly entertained and informed me, and a lot of people, with your careful and expert work. Have a great Christmas and see you in the new year! Cheers

Well done! Enjoy your videos tremendously. Happy holidays from Virginia USA.

as always a delight to watch your work David! Merry Christmas !!!

That’s sure a beautifull radio, I really enjoyed watching restorations, thank you so much for sharing, I wish you and your family all the best and have a happy new year.

Dave - in my opinion you are one of the best vintage radio repair/restorers on YT right now. Very enjoyable to watch and learn "how to do it" in your videos. I wish you and your family a super Merry Xmas and a safe Happy New Year. :-)

These radios are windows into the past, that’s what makes your work so interesting. Thanks for another interesting video.

Your an amazing Technician David and it sure has been my pleasure viewing all your work this year. Hope you and yours have a wonderful Christmas and a Happy New Year mate.

Another great one David! I would like to whish you and your family all the best and a happy new year! Best Whishes, Moshe.

Nice work as always! Did a nice job! I enjoyed this video!

One more time, you nailed it! Happy holidays and all the best for the next year!!!

Nice restoration! Looks neat!

Hello David, All the best to you and your family for the festive season. Your multi camera shots and overall video production are a real credit to you. Congratulations and please keep up the good work. You have created a wonderful channel. Cheers from a smokey, burnt very sad Sydney, New South Wales.

Love your laid back style

good technical info always look forward to your videos

David, I have been watching your videos for about 2 months now. I appreciate that you are learning electronics but I believe you have a gift for it. I am retired and I have extensive but stale experience in electronics too. I really appreciate the high technical content and theory that you present when repairing these items. Also, I am amazed at the beautiful finished product. Keep up the great work. I have been repairing several radios, all tube models and I am inspired to continue with them even when components fail and I have to use theory and measurement to figure out what went wrong. Your work is inspiring. Thank you for you presentations and keep at it! JH

Super fun as usual. Thanks for sharing. And, Merry Christmas and Happy New Year to all....

Really nice, thank you. From here in the UK, Happy Christmas and have an excellent New Year.

Merry Christmas: will be starting my hamarlund 129x in the spring thanks to your inspiration.

A neat looking looking little radio and a job well done on the repairs to make it operational again. Best, Don

Very Very nice work sir! It looks and sounds fantastic! I love your technique and gentle voice, and general way you go about these. Such a great video. What a beautiful radio.

Looks & sounds Nice. Merry Christmas and Happy New Year to You & your Family

Very careful and superb restoration. I enjoy your videos David. Merry Christmas, have a good new year.

Thank you David, I just picked up three 11-20 in the last 2 weeks, I looked on RU-vid for repair videos for the Kriesler 11-20 but it looks like you are the first, Now looking forward to working on mine, just waiting on some parts.

It is encouraging to see you do this and even though handicapped by having only minimal information/specifications, you have still come up with a nice sounding old tube type radio. I now know in Australia it is a Valve type i suppose, but all the same, any radio that old that works that well and looks that neat is well worth owning. Good job once again David Tipton.

Another great job Amazing skills

Lovely job. Really enjoyed this video. Greetings from London.

Merry Christmas David! Santa's coming on christmas eve to Sweden and I'll remind him of that brilliant aussie bloke. Cheers!

Well done David, have a great Christmas

Thank you your work. I enjoy watching your video. Look forward to seeing more in 2020. Merry Christmas and happy New year. Greetings from Moscow.

Thanks for bringing me your work, I very enjoy watching you restore these old radios. 31:10 the female voice is saying: " xxx doing business. xxxx.. is very simple " it is a Cantonese program. Merry Christmas sir~~

Hi David. You do nice work. Having just built a 1 RF / 1 IF home brew superhet, (6BAC, 6BE6, 6BA6, 6AT6, 6V6, 6X4) I have been thinking about the issue of isolating the tuning condenser. I think the isolation is two fold: One to allow the ground currents to be directed using wires rather than interacting with other ground currents in the chassis and two, possibly more important, the condenser is a microphone in that vibration will modulate the tuning. So vibration from the speaker can cause tuning modulation at audio frequencies, resulting in a rough sound methinks. I have mine hard mounted and am experiencing some issues that I think may stem from the above considerations.

Hi David just an update on the Collier & Beale set I'm restoring.. I already powered the radio up with a dim bulb tester and at first it didn't give any sound at all ...and guess what, the output transformer was open. So this video is actually perfect timing! I just experienced what you experiened in this video but it took me ages to figure out what the problem was until now. Luckily, I bought another set that had a speaker with a good output transformer and used that to test my recapped radio. Now it works fine and produces great sound. Thanks for sharing this. Btw, congrats on the steady increase of subs. You deserve it! Merry Chritmas and a Happy New Year!

Another great job David. Merry Xmas to you and your family as well. Stay safe.

Great restoration David, the set cleaned up nicely too. The negative bias voltage derived via a power transformer winding for the output valve is quite a common arrangement, most of the NZ valve sets I've repaired are the same, it fooled me initially until I figured it out. I liked the way that capacitor failed with a 'crack', normally for me they short or getting stinking hot! Happy New Year and look forward to more video's in the future 👍☺

Nice job on that radio. Looks great. Glad you got it working good. Have a very merry christmas and a happy new year. Take care, Great video. 😆

Verry nice plum pudding ;-) . thank you for the video . merry christmas to you greets Uli

Amazing work ...have great happy new year

Happy New Year David!

That is a good job dan David, an interesting video as usual.From Claes.

Thanks and best wishes from Scotland

You do know what your doing dont keep knocking yourself. Good on ya mate.

Another enjoyable and informative video David. If it's a plum pudding needs a 6d piece (6 pence coin) putting in it 😆😆

Hello, my name is Cleber, I am from Brazil, I follow your work, congratulations !!

Thats a nice plum pudding and a good job well done David. Have great Christmas and all the best for 2020...................................................................Berni

Those Kriesler purple bakelite cases really look good. I think I'd really like to find this SW one under my Christmas tree.

Very nice ! I can listen to Radio New Zealand late at night here in the USA :)

A suggestion, instead of mangling those threads with pliers. Try threading on another nut. Then you can turn the nuts against each other to turn the screw body. Tighten the top nut against the lower nut to adjust clockwise and turn the bottom nut out into the top nut for anti-clockwise. Hope that makes sense. :) Really enjoying the content!

Great video as usual. Although you indicated that there was a difference between yourself, fellow Australians and New Zealanders, I really couldn't discern a difference. Though those that live in the northern US states say they have a hard time understanding we southerners, I have a hard time understanding those from the New England states. Oh well. Hope it isn't too hot for you there. Merry Christmas to you and family!

One of many nice tube type radios. Those are from the good old days. I don’t see a year, but I’m going to guess this one’s a 1946. A time in which American workers took their time and pride into these wonderful, high-quality works of art. Try to put this radio and a modern Chinese radio side by side, we both know which one ☝️ will sound better. From the steel chassis to the tuning gangs, high-quality speaker and metal knob shafts, to the dial cord to the dial light, and the glass face, this radio is like a ‘57 Chevy. All this under a very handsome Bakelite case. Painted on numbers, yes, when everything was better. This radio is worth teasing your kids or wife with. Just set it on the table and call everybody to Christmas 🎄 or Thanksgiving dinner. Yes, a little plum pudding. All the nice radios of days gone by. Bakelite or wood, they’re really the radios 📻 that should be in houses 🏡 across America. I think 🤔 they should be a living room radio. Not for the garage, bedroom, basement or shed. A basement may be fine if there’s some kind of value that I know, but don’t know how to communicate it. Simper way to say, if the basement is converted into your living room. Some unconventional houses are done in ways some people don’t think are possible. I like that little Spanish jingle, which starts at 12:47, and lasts until 12:53 on the video timing. Can you tell me who it is, or the name of the song? I’m guessing Selena. Please keep these great radio videos coming. If you come across any cardboard cased radios 📻, please don’t turn them away as some RU-vidrs do. They are probably 1940’s and 1950’s radios, which are much sturdier than Crosley record player radio stereos today, produced from 2009 to present 🎁. These 1940’s and 1950’s cardboard cased radios are still a major piece of history. These could be 1960’s. I’m a poor guesser at when cardboard cased radios, record players, and record player radio combinations came out. Great 👍 videos. Keep ‘em rollin’.

GREAT radio dave

32:30 The broadcast range starts about 5 Khz short of the bottom end of the band(535 Khz for the band, 540 Khz) for this radio, but at the other end(top of the band) goes 35 Khz into the Narrowcast range above 1605 Khz(this set tunes up to 1650 Khz).

Hi David, Nice work and video! I have just finished one of these sets myself and it was interesting and amusing watching you find some of the same issues I found, including the output transformer. I managed to salvage mine - the open on the secondary was on the very inner winding and I managed to hook an and out and reconnect. Cheers!

Fascinating, I've never seen a Receiver with abbreviated State names for bands. I finally figured that out. U S. broadcasters, hammers. radio types transmit licensed call signs not abbreviated, state letters.

Interesting scale, covers the whole world

Top job well done as always from you Very nice looking radio,Australian radio's i reckon are better looking in style than the ones we get here in ZL .Enjoyed

I like this work

Thank you David, another great project to follow, can you slow it down a bit! Usually you have a nice and slow / easy flow to your commentary which is part of the charm of listening to you, might be me, but sensed a different style of delivery in this video "rushed" . Hope you don't mind the feed back, hope you and yours have a lovely Christmas and a great new year and once again, thank you for all your great videos. Graham from the UK.

Nice working

Radio New Zealand International are still broadcasting, unlike Radio Australia. I still listen to them on my FRG-7. They started broadcasting DRM digital regularly a few years ago.

As always David , a masterful piece of restoration.. The Kriesler is the same age as I am.. Perhaps if I pop over to you in Oz, you can do a restoration & make-over on me to give us a new lease of life ? My better half say's I need at least an alignment job so I can receive her instructions clearly.. Personally, I think I'd prefer to stay slightly 'off' frequency !

Very good David! I've enjoyed the restoration. The only thing I've noticed is that you didn't mention if you care about the new Capacitor's outer foil connection... Old (Wax) cap's had a black line at one end and even stated "ground" or "outer foil", new cap's don't (maybe nowadays this is no longer needed as the components are placed on printed circuit boards) But in old radios, the outer foil can be an excellent hum antenna if connected backwards.... Whit the help of an oscilloscope and your own hand, you can easily find the outer foil in new capacitors so you can mark it in order to respect the original connection. Thank you for sharing!!! Happy new year!!!

I have a couple of those plum pudding radios I picked up cheap at the HWS auction in Brisbane. Haven’t looked at them yet. Your video gives me the confidence to tackle them! Only problem which I don’t think you encountered was both mine have cracked or missing Bakelite strips on the speaker opening. I’m not sure how to handle something like this. I’m sure there are restorers who can make substitutes pieces and glues them in so as you’d never know, it I think it’s beyond my skills. I bought the second radio for spares to fix the first, but looking at them they are so beautiful I can bring myself to rat one of them to fix the other…

I just discovered from the Hallicrafters Groups site, if you are cleaning plastic covers (side with no lettering) try dilute toothpaste with a cosmetic wipe. Not fancy toothpaste, ordinary toothpaste. Did a great job on my s meter.

@46:13 David I have to point out that even though the peak is correct you could have the situation where some of the IF coils have drifted up from the 455kc and some have drifted down. This would give the peak correctly but you cannot know if that peak could be higher unless you trimmed each coil. This could also affect the selectivity particularly on SW.

Love your videos. RNZ could have been 9700kHz to the Solomons/PNG or 9765kHz to the Pacific. I can get their broadcast targeted to the Pacific in Southern California in the afternoons, but it's weak. The Asian station could have been China Radio International on 19m band; CRI took over some of the shortwave frequencies Radio Australia used when they shut down their SW transmitters.

good to see u put a mains fuse in, definitely could save the trani . you can peak the short wave bands in the same way as MF. ps 6x5 rect tubes with flat plates are known to short :)

Great job David. Shame about the broken adjusting screw, and the open circuit output transformer, but you can’t win them all! Case polished up a treat to complement all the hard work you did inside. Spreadsheets for transformer specifications? I vowed I would never even look at another spreadsheet when I retired lol. Cheers Lynton

Another masterful job Dave! How did you get the cabinet to look that great?

That was Vietnamese. My wife is from Saigon,. nice job again.

Another fascinating restoration David, your transformer load calculator spreadsheet looks very useful, is it available for download anywhere? Happy Christmas.

lovely restore, need to get a valve radio :)

Radio beauty. I even like to restore such a radio ... !!!!

Re the dial pointer, keep in mind that station separation was changed from 10Khz to 9Khz in 1978 so the pre-1978 dials are now out of whack to that extent.

Hi David from UK, thank you for another great restore. As a newby to the hobby could I ask you to show where you hook up the signal generator for the different stages of alignment also can I say how helpful it is when you show the schematic in relation to the part you are working on. Looking forward to the next restore merry Christmas to you and yours.

Hi Dave , Why didn’t you rewind the speaker transformer instead of looking for another ? Again it’s wonderful video , thanks for sharing and we wish you merry Christmas and prosperous and happy new year 🙏

Hi David. Quick question. At time 20:51 in this video you mentioned a solder product called Quibbs or Quidds, a pre-tinned wire. Would you give us the exact name so we call look them up on the internet for a purchase. Thank you.

Please can you give me the selution to avoid the nois in AM radio by the effect lighting fiting or the electric generator sorry for my English thank you

35:08 If you turn the schematic representation of valve 6X5GT, you get a "sad face"!

The analog meter you were using to measure the bias may have been loading the circuit, giving you the lower reading. The digital meter is probably a 10 or 11 meg per volt where the analog is probably 20 to 50k per volt. Nice work! 👍👍

Consider rewinding the primary. I started rewinding transformers at 15 yrs old and once you do one the fear goes away. Also your radio is more genuine.

You should watch the Mr Electricity guy on youtube. I seen him rewind a transformer like this, quite interesting. Good vid BTW.

muchos modelos parecian tostadora de pan. 👍

The rubber grommets under the tuning cap are for RF isolation, you can't have any connection between the tuning cap and the chassis.

can i ask where can i get some of those grommets you are using for the tuning forks...?

I came for the plum pudding

How about a link to your spreadsheet? Good job though!

Perfekt !. What to do?, Can be replaced with extremely difficult to get (in Poland) EBC41 tubes. (Google translator;-(

An odd looking radio, but working well after you set it up. Is it a hard early plastic case? Strange colour they chose for the case, but then I was not around to see what the trend was back then.

you should check mr carlsons lab, he makes a lot of tube equipment videos, and he has a cap leakage tester he have shared, and you can build it yourself, a lot of good info there
