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

This old receiver came to D-lab in dyer need of repair. It was very weak when it arrived. Due to it's condition, I hesitated on spending too much time on it. Lucky, it only needed a few tubes and resistors. Sprang to life. Ready for another 50 years of service.

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!!!!!

Some good tips on soldering in components. Thanks.

[@langhilau]

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.

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 :-)

[@zzy09azy]

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.

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

[@mikesradiorepair]

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.

Thats super cool man. Gotta love skip land!

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 :)

Good video!

[@MichaelLloyd]

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

Thank you sir, always good to hear from a fellow Ham op

[@fabinhoosmar]

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

[@isoguy.]

Thanks for sharing

[@Ira06002]

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!

[@DeadKoby]

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.

[@kornami8678]

No paper caps in that radio?

[@frumpeting]

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

[@plunmeister1093]

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

[@willrobbinson1]

in circuit they may test lower value not higher

[@harrystevens3885]

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

[@d-labelectronics]

Cool deal man, welcome aboard!

[@bizman45390]

The Magnolia State is Mississippi getting on down

[@russphilly]

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

[@olenamcquagge7777]

Mississippi is the Magnolia State.

[@animalcorvair]

i hear him on chan 15 all the time lol 27135

[@stormchsr1017]

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