Hey, All,
'Been working on a (late) model 60, and I have all caps and all bad resistors replaced.
When I first got it running, it worked so-so, and after about 45 min the osc. quit completely, and found I had the classic coil problems that I've been reading about in this forum. Great info, BTW.
Anyway, yet more questions:
-- One member here thought that anything from 34 to 38 awg would work for rewinding the primaries on the osc and antenna coils. Ron, I know you have said that 38 is what you use. Any known problems caused by using 34? I would think that the issue is mainly one of getting enough of the turns onto the right place on the core, but I'm weak in my inductance theory. 34 is way easier to get in the time I have, and would like to do the rewinds either tonight or this weekend.
-- The secondary on the 2nd I-F coil (Item 25) measures 45 ohms instead of the 85 ohms shown on the schematic. Problem?
-- When the radio was working after the rebuild, adjusting the I-F trimmers too far one way would cause motor-boating to occur. Is this normal, or due to the above coil issues?
Thanks!
Scottie
