Model 38 serive bulletin No. 120-c Alignment
#1

Just finishing up a Model 38. Looking for information on alignment. I have the ryders info about compensating condensors and placement so was able to do an alignment of the IF to 460 Khz. However I dont seem to be able to get the alignment to track on the dial. Also any information on how the band switch works, there is nothing changing the oscillator circuit that I can see. Just adding two caps to the rf coil seconday top and tap. Broadcast band is working but police sw is not. Just gets oscillations. Coils all check ok.
Thanks in advanvce to anyones help.
