Dial Calibration Problem on 41-295
#1

I'm having a problem calibrating the dial on my 41-295. When I adjust compensator 20A and 10A with the dial set at 1500 KHz, I find that the adjustment to 10A (adjustment on the tuning capacitor) has little or no effect. With the generator and dial set to 580 KHz, 20 seems to adjust normally. The end result is the dial tracks normally, at the low end of the broadcast band, but begins to lose it's tracking at 760 KHz , and the station that should be received at 760 KHz, now comes in at 780 KHz. The adjustable 10A appears to be intact, but not functioning properly, even though the mica appears to be in place, and the adjustment screw appears to be the original slotted hex head screw. If you fully tighten the adjustment screw the signal drops very slightly, but as you loosen it, the volume returns slightly but never gets any stronger through the remaining range of adjustment.

What else can I check? All the tubes in the set test good to excellent.
