PLEASE NOTE: This is not a tech channel, but simply a show-and-tell. It is not designed to give advice and support on vacuum tube amplifiers but to show what I get up to each week in the workshop.
I deliberately keep tech talk to a minimum, or at least to a point where it’s understandable to the casual viewer. There are other channels more suited to that level of detail.
I do not do reviews, either paid or unpaid. My opinions are entirely my own and do not represent those of others.
All comments are welcome but those deemed unhelpful, rude, inappropriate, or unsavoury will be reviewed and possibly censored.

It's amazing that the Matamp left the factory with the wrong rear faceplate and tubes installed. Glad you finally got it figured out!

Mike from Modulus must have weight of world on his shoulders, but always gives you his time, hes a good guy

@TheMorganOrgan 13 дней назад

Agreed, great company and brilliant service.

I love how your chopstick looks like something out of Harry Potter… “Audio reparo!” 😂😂

They’re actually Ken Homm Signatures, I’m not joking !

Thank you for an interesting and varied video. From a factory incorrect amp to an ancient Heathkit tuner - that's great content. It would be great to see you work on the Heathkit if you decide to record it. The twice a week, 20ish minute video is a great format for your channel, helps to keep the flow going.

Glad you enjoyed it!

@carstenmarcussen6565 16 дней назад

Good work with tracing down that "amp-bug". It turns out the bias resistors has never been correct from the factory. That can happen but still amazing hahaha :) Best regards from Denmark

That's a "go" from me on the radio service.

I'd like to see the Heathkit serviced.

Me too! "Magic Eye" demo.

Built one of the HeathKit transistor tuners in 1970. The ferrite cores arrived broken and so my girlfriend (later wife) glued them together. Had to send it back to HeathKit for alignment which they did but still using the glued cores! Tuner worked well. I wonder where it is now.

I'd love to see you working on the radio receiver. It's a shame that Boris the spider lost his home though.

re: resistors.. I don't trust the colour bands and usually pop them on a meter before using each one. On my last build I used RN65D metal film resistors which dont even have colour bands, the value is printed on the resistor body. Bit expensive but very quiet...

Matamp section is a masterclass in good problem solving. I used to work in problem services for people with disabilities (I.e staff problems, unhappy staff, parents and users.). And your process was same. The other element that you may also use is spend time thinking about all the possible options (assumptions). Many people look at info and quickly go to a solution. Also cf line checking a large (24 channels+ eg) sound system. Fascinating stuff ✔️

@marvinmitt4575 15 дней назад

Thanks for nice channel, subscribed! Just a note from someone who's been on the lookout for new gear. As for oscilloscope I would go for the new Siglent SDS804x for about the same money and get it unlocked to 824x if that's possible (too new scope to tell). For the iron Aixun T3A with original JBC T245 tips is a killer for 140€.

@DornAndGrant 15 дней назад

Would like to see the hearhkit service!

@MyNameWasTecho 16 дней назад

You’re right! I thought “I DON’T BELIEVE IT”, then you explained and I thought “oh, that makes sense” 😀. I know many a Les Paul has a name, but I shall now always call the amp “Victor”. 🤣

I love these videos, keep up the great work!

@giulioluzzardi7632 10 дней назад

I bet even " Colombo" could'nt have solved that Matamp mystery.

@David-gx9lh 16 дней назад

Chris, when it comes to 6v6 tubes, which do you regularly use? Thx.

@gringopig 16 дней назад

Good idea to actually sample measure before adding to stock

@jjsant3250 11 дней назад

Did you measure the ratio of the OP tranny? That would confirm which output tube it was truly made for since 6V6 differs greatly from EL34. Bias is only half of the design story.

@Jonathan_Doe_ 16 дней назад

Either someone’s modified the switch, or they decided to change the design/ran out of ultra linear transformers, but already had “ultra linear” silk screened on their chassis.

@tom_bluespower408 15 дней назад

Any experience with the RS all in one digital soldering irons, or best to go with the digital station as you suggested for the extra £30?

@RiftAmps 15 дней назад

I haven't tried that one so couldn't give a recommendation. I only know what I know!

@tom_bluespower408 15 дней назад

No worries, thanks for coming back and for the content!!!

@marktierney3938 11 дней назад

Was the owner of the Matamp the original owner? Or had it been bought used? I have a very similar amp, mine is a prototype. It has 6v6s and sounds fantastic but the back plate says it should have EL34s. I think they often used to make alterations on the fly at request from the customer so could be an after sale factory mod? Excellent content btw!

@RiftAmps 11 дней назад

It was originally owned by a Matamp dealer who kept it after his shop closed down, who then recently sold it to my customer. I suspect you're right but have no way of confirming. It's a great amp and my customer is very pleased with it

@NotMarkKnopfler 15 дней назад

Heathkit +1

@ChrisHopkinsBass 16 дней назад

Sounds like someone had a brain fart in the factory and put the wrong backplate on….brilliant demonstration of the diagnostic process

@adewillson3396 15 дней назад

Heathkit yes please

@AnyMajorDude-et2ub 7 дней назад

Please do a nice long vid on that Heathkit. I wish our young people of today would get off the brain numbing computer games, and get into hobbies like this. Besides being fun: they'd actually learn a skill and use their brains.
