Philco 91 Code 126
#18

More progress, if anyone's still reading:

I pulled the oscillator coil back out again. This time, I removed five more turns as planned. Reinstalled.

The 1200 kc signal from the signal generator was now coming in around 1140. This was a good thing, as I was able to (finally) turn the high frequency oscillator trimmer in somewhat to bring the signal back up to 120 on the dial.

Meanwhile, down the band...660 now comes in around 684 on the dial.

I think this is the best that I am going to achieve with this one, and have declared victory. Icon_thumbup The 91 is very sensitive, even with a temporary 20 foot antenna strung along the ceiling of the basement. (I have yet to put up an outdoor longwire at this location; this will be a spring project.)

Things that remain to be done: New rubber bushings under the tuning condenser, giving the chassis a good cleaning, and installing an 8 inch speaker in place of the stock 10-1/2 inch speaker (this chassis came from a console, but will be going into a cathedral cabinet).
