I am working on an earlier model 60 (pre wave trap).  I have replaced all the caps and a few our of spec resistors.  All the tubes test good (and I have also swapped tubes from a working 60).  The speaker, output transformer, and assoicated wiring is good (I also swapped a working speaker and related parts from a working 60.)  The set powers up, and with an antenna attached will receive stations along the entire dial, but the volume is a whisper.  The volume control works and will take the volume from 0 to a whisper.  The volume pot is good and I also swapped a working pot from another radio with the same results.  Touching the volume pot connections does not produce a buzz or hum.  I am at a loss.  I compared voltages to the working 60 and nothing iappears to be alamingly different.  Since it receivce stations does that mean the various transformer coils are ok?

Ideas?
