Back from the dead: 1946 Crosley 56TC (with pics)

Post by stringbender31 on Sun Nov 25, 2012 5:25 pm

I picked up a decent-looking 56TC a few months ago that was D.O.A in hopes I could learn a few things & get it playing again. I think it must have sat in an attic or closet for a very long time because most of the wiring was rotted and fell apart when i moved it. (And it had a lot of dust in it.)






I had to fabricate a new dial lamp holder since the the wiring on the original was trashed.





The wiring wasn't the only thing brittle on this radio, one of the lugs on the rectifier socket broke off when I touched it with the soldering gun, so the socket got replaced too.




So, I replaced the rotted stuff, recapped it, changed some out-of-spec resistors & power it up for the 1st time in who knows how long.
I brought it up on the dim-bulb, the tubes and dial lamp lit up but no sound. Checked voltages and found I had no B+, which I learned was caused by a bad field coil. (Which also made the speaker useless) I replaced it with a power resistor and permanent magnet speaker.




Fired it up again & to my surprise, still got nothing. After a lot of trouble shooting, signal injection, signal tracing, rechecking my work and a bunch of head-scratching, I pin-pointed it down to this little trouble maker here:



I didn't bother with this when I recapped it because I was always told that these rarely go bad & no need to change them. I learned that "rarely" does not mean "never" lol!

Here is the underside all finished




I'm happy to say it is now playing and sounds fantastic! I aligned it & let it play for over an hour with no issues whatsoever. It pulls in lots of stations with loud, clear volume.





Here's a couple shots to show how much dust was inside when i first opened it up. Needless to say, both the cabinet and chassis got a thorough cleaning!





I learned a lot with this radio & I'm very happy how it turned out (even though I'll admit I wanted to throw it out the window a few times Mad )

Hope u guys enjoyed it! Sorry about the blurry pictures

Nice work! I had one of those mica caps fail in my first console restoration, a Motorola 51-L

Great job, looks like you also replaced one tube socket.

Every time I see a radio with wire covered in rubber insulation it sends cold chills up my spine and flashback reminders of the old Joan Crawford movie line, "No wire hangers!!!!" .

Great job on the restore.

Thanks guys. Up until this one, a simple cap job was enough to get the radios going that I worked on. This radio was a challenge for me and helped me learn quite a few new things. I have been working on it for a few months off & on, & I was really happy to hear music finally coming through it! Now I'm ready for the next one Very Happy
