National NC-88 receiver repair How to change resistors in tube radios 

My National NC-88 plays oldies in the shed daily. Restored, it's glorious. At night, I can easily listen to the other side of the planet...

If you have ever visited Mississippi in the summertime you would likely see Magnolia trees in bloom everywhere. They have a lot of them for sure and are proud of them no doubt, so much so they call themselves, the Magnolia State.

I think the "I don't know, but he's gettin down there" was the best part LOL!!!!!

That is a great tip on the resistors and I was just looking at an ashtray full of bad resistors I had change and as surprising number of them where the yell band as you pointed out. A great tip.

Some good tips on soldering in components. Thanks.

Great repair of that old National. Nice tip on the resistor replacement on those cans. I have a NC-98, think I did a video on that one.. Thanks for sharing and don't get down too far :-)

As usual, a beautifully informative video. But, I think I'd be a bit more careful in scraping clean the component leads over the chassis. It might leave small metal fragments where you don't want them.

Got to love it when it's a easy one. Besides electrolytic capacitors the old carbon comp resistors are the next most troublesome components there are. So unreliable I did a whole video on them. And LOL, I think I'm currently listing to the same "Magnolia state" guy that you had on the radio.

Hi D-Lab, I have a resistor that gone bad, Its from an old Pioneer amplifier SA-410 the problem is that my resistor is an old one, I can't find it anywhere, Is there any alternative, How it should be nowaday, So i can replace the bad one? Please i want an advice, I'm not an expert. On the ceramic resistor that have 3 pins there is some data: R71 0.22 x2 (2w) Thakns a lot in advance for any informations, The sound i hear from it nw comes only from the right channel :)

That was a first class repair, but that's what I expect to see from your site. BTW- the Magnolia State is Mississippi. I hope that was a CB frequency :) 73 NE5U Mike

Great vid and thanks for the tip on the resistors. VERY useful :-)

DUMB QUESTION TO ASK: Did you replace the old resister with the same one (but newer) or did you modify and change the resistor? I'm very new at this and trying to understand if/when I do replace resistors I replace them with the same color code as noted in the schematic. Your video was very helpful for us beginners in radio restoration. Thank You!

Bom trabalho colega, resistores com tolerância de 5% são indispensáveis nesse tipo de aparelho.....

Thanks for sharing

If you measure resistors in circuit arent they going to show the attachd circuitry too?

Good video!

There's some techs who swear that carbon comps "sound better".... I'm guilty of using metal film for durability, although I've been getting lots of parts at the surplus store now... so that's a mixed bag.

No paper caps in that radio?

I think it's time I subscribed..........And now i have.:)

I've just inherited an NC-98 and hoping someone can point me to where diagrams are for these old radios?

get down! to the MagnOlia statE! 10-4 !

Mississippi is the Magnolia State.

The Magnolia State is Mississippi getting on down

i hear him on chan 15 all the time lol 27135

why do skip cb radio guys always sound like they are all from the south?
