How can I Find help to repair an old-time AM Silvertone radio and the best place to buy tubes for it? Answered

Maybe you can help me. I live in Kobe, Japan and am trying to restore a Silvertone 6327 (1947) radio (American). Recently I tried to replace the electric cord that plugs the radio in to a wall socket (the line cord). In doing this I soldered the "radio" ends to two terminals on a 35Z5GT tube. I then plugged the radio in. turned it on, and waited for it to warm up. At first the radio simply made a low humming noise even when I tuned it across the dial (no reception). After about two minutes the 35Z5GT tube briefly lit up and then died (like a "nova"). I'm afraid I may have done something wrong when I tried to attach the new cord line to that tube's terminals. I need to find someone who knows about repairing such a radio to see what the problem is. I want to do this before I replace the 35Z5GT so I don't just keep burning it out (which may happen). Do you know of any such radio repair shops in the Kobe/Osaka area? By the way, I know the radio works as I tested it before I did my "repairs." Also I would like to know is there a source of old tubes anywhere in Japan so I don't have to have them shipped from America? I have read the instructable on how to restore old-time radio; it was very good! Maybe the author of that piece can help me. Below is a picture of the radio from the Web (mine doesn't look quite that good. Thanks for taking the time to help me on this if you can. Bob Austenfeld


hello i was the author of the Restoring an old radio I was the same as other people (scratching my head) I just looked at the schematic and it said that one lead went to the 35Z5T. The other however went to the Switch thats what happened sadly you must have accidentally put the wrong lead on the tube. Heres a schematic ( http://www.nostalgiaair.org/PagesByModel/492/M0017492.pdf ) I have heard about the earthquake and I just hope you are alright along with everyone else in Japan!

Sanity check: When you say "In doing this I soldered the "radio" ends to two terminals on a 35Z5GT tube", is that where the old power cable was connected? (I would have expected them to go to a transformer.)

I still have my grandfather's old cabinet radio -- minus the turntable that it originally had, alas -- and last time I turned it on, it was still working. I've been considering making a minor modification so the turntable position on the input switch instead selects a line input -- which would be fed from an MP3 player loaded with old-time radio programs. Instant time machine.

Lots of the old radios had not transformer.  Google "AA5 radio" The tube filaments were in series.  NO isolation from the mains.  Lots if shocks.

Most people (myself included) suggest running these radios thru an Isolation transformer.  Much safer to be around them and safer for the radio.  They were meant to be run on 110 volts and most places in us have 115-1120 volts. 

On you instant time machine several threads on that forum about exactly that.

Go to this forum  There are guys on here that live for the old radios.

You have a nice radio and it would be nice if it were brought back to new.  If you haven't tried it out yet then please don't.  Old capacitors dry up and short out.  There is a way to turn it on to check them without hurting anything else.

Show them what you have and give them details of what you need done.

Tubes are still easy to find.  They can help you find what you need and the best place to buy.

Good luck.
