Actually, I replaced every single resistor on the main chassis except one, and several on the tuner sub-chassis that measured out of tolerance.
I may actually be chasing my tail now. I had it running for a couple of hours while I was fiddling with the alignment (again). When I shut it off I decided to get brave and carefully touch the 15k resistor. It was on FM for quite a while so I figured it would be too hot to touch for more than a split second but it really didn't seem that hot. I'll try it again the next time I have it running but if it really isn't that hot I can't explain how it could be dropping 151v, which means it's dissipating 1.5W, and not be quite hot.
But now I have another problem [Image: http://philcoradio.com/phorum/images/icons/sad.gif] I'm not getting anything but a nasty sound through the mixer/oscillator. I need to get this thing working and leave it alone LOL. It does something different every time I work on it!
I think I'll think about that one while I remove the dial backplate and paint it. I put some tape on it so I could mark various points on the dial and when I removed some of the tape some of the paint came with it.
I experimented with several different types of paint and it looks like Rustoleum Copper comes closest to matching.

Thanks to all for the feedback. As Arran said, it is probably an older replacement and yes it has a grid cap so I will ...georgetownjohn — 09:32 PM |
