42-380
#1

    Hi Folks,

I have a 42-380 (who doesntIcon_biggrin). I am a newbie, and once had Ron do a 41-608 for me (still going strong..)

I recently finished repairing a Delco 3205 (32 volt) and taught myself a few things about working on a tube radio. I have Delco 32 volt generators, hence the interest....

NOW, getting on with it...I am working on this 42-380. I was given one, and after taking out the chassis, guess that the electrolytics went, shorted out the xformer, and nearly caused a small fire in it. Suffice to say good for parts. I got another chassis and after cleaning the tube pins, sockets, and double checking for obvious problems have powered it up successfully, and all tubes are OK, and I have 60hz hum, if I probe the vol switch. After poking around some more, I find that the screw adjustment on this rf can is all the way up. I discovered that if I touch that screw with a finger, I get a buzz as if its trying to use me for an antenna, but no stations come in.

I will put new electrolytics in and recap for the first time. By doing so , do you think I'll be closer to a working radio?

Thanks for putting up with a dumb question.Icon_mrgreen
