I am reviving a Philco 46-420 and I have a question about the AVC circuit. In previous restorations I am accustomed to seeing an RC circuit filtering the audio signal off the top of the volume control pot. In this model schematic I find the “R” but not the “C”. Can you instruct me in how the AVC works in this model? Thanks for your help. RadioBob
