Reece. Appreciate your post. A lot of good info in there.
I had noticed on the radio itself that cap #41 isn't grounded either. There's just the positive lead coming out of the can and I can see no evidence that there was any other wire soldered where the negatives were on the two others. I wasn't sure what to do when replacing that one. Should I ground it to the chassis or leave it without a ground like the original?
I got a cap list together tonight from looking at the actual caps and have the mfd values for all of them. At least half of them are different from what's listed on the schematic and parts list.
There are a bunch that don't have any voltage printed on them and there doesn't seem to be any voltage in the schematic or parts list for them either. I think I vaguely remember coming across a vintage radio web site where you can order caps from that said something about all the small caps being a certain voltage for that model radio. Does that sound like it makes sense or am I making crap up?
Case be the later, is there a way to determine the proper voltage rating for these?
Oh yeah, the phono input. I looked for that on the diagram as well but couldn't find it. I read somewhere that the rca jack on 39s was indeed an input and it was original, but was a sales gimmick more than anything because television was coming right around the corner and the presence of the input was somehow supposed to convince people that these radios would be compatible with the new technology. Not sure how that was supposed to be, but today it is a great thing to have on there to allow a CD to play (in mono) or even better, a guitar.
I won't be turning the radio on again until I've got it recapped.
