Restoring a 39-7
#16

I prefer to keep rubber and wires separate. Icon_lol

Thanks, I'll see if my local electronics shop has any...

Edit:

No luck. I have to go to the Internet. Any decent sources for these? I cannot locate any 6000pF caps, only 4700pF.

So what can I do? 4700 is enough, 10000 too much, or should I wire 3 2200's in parallel (I'd rather not tempt the fates of MTBF this way)?

Also there is one other silver mica capacitor in there - it's part 6A on the schematic. The problem is it's listed as a 20mfd device and there's no way this is 20mfd, it's just way too small. Elsewhere on the schematic it's listed as 20mmfd, which makes a lot more sense for this type of capacitor.

It sings again!

After putting up with the repaired speaker that tended to muddle the sound and distort at medium-high volumes, I decided to take a closer look

The speaker was slowly disintegrating - small cracks were developing, and the most careful light touch caused the cone to split.

So I had the speaker reconed.

It's now a whole different radio. Plays loud, tight, and clear at all volumes.

I probably put more money I to this than I should, but it would have been a pity to leave it in such poor condition.

Speaker looks very nice. Who did you send it to for reconing?

Nice set! You've got the delux model with the brass escutcheon around the dial. Many years ago I had the chairside version of that set. Wish I hadn't sold it! Good player and very sensitive too.

Actually, this one doesn't. It's pretty plain. I have a nearly identical model with the preset tuning buttons and the brass escutcheon though. You are right about the play quality and sensitivity though. A solid little radio. The guy who had it before me wrote 38-12 on the chassis, but it is a 39-6 as far as I can tell.

Edit: no, it isn't, it *is* a 38-12 chassis. Just double-checked the schematic. Someone put a dial from a 39-6 on it and stuck it in a 39-6 cabinet. >:-(

Aw crap! Just noticed I posted about the the speaker in my 39-7 thread. At least the 39-7 is a real one.
