Model 38-17, Code 121 schematic
#1

I've recently acquired a nearly perfect Model 38-17. The chassis is clean and the wood case is nearly perfect. I've noted that there is no listing of the 38-17 in Nostalgia Air or in Ron's "Philco Radio 1928-1942" bible. I believe electrically this is a 38-15.

I'm in the process of replacing caps and out-of-tolerance resistors and have run into a minor problem. The 38-15 schematic has both detector diodes connected together. My 38-17 has them separated with one dedicated to developing the AVC signal. From other schematics, I can guess the resistor and capacitor values for the AVC circuit but I would like to get the actual schematic, if possible.

Any suggestions for obtaining a schematic that matches my radio?

Thanks for your help.

Don
