Atwater Kent 55F
#17

I was able to repair the RF transformer.  The break was right next to the terminal so not much of a problem.  That allowed a MUCH greater sensitivity.  by increasing the spring tension on the tuning capacitor shafts, they settled into a more centered travel giving stations all accross the dial.

This is the first non AGC radio I've played with and can see/hear that AGC was a tremendous improvement in the day!  The Philco 96 TRF performs so much better than the AK 55.

Voltages are indeed much higher than they should be.  Interestingly, several resistors had been changed a long time ago to higher values, perhaps to compensate for 60 cycle rather than 25.  Not sure what I'm going to do as it will take a pretty good resistor to drop the line voltage.  Since I'm not too impressed with its performance, I may just leave it for an occasional demonstration and keep it for show.
