Rider 4-13 unable to locate where wires go for part #7210 2nd I.F. allign cond.,(picture in book) somebody cut wires off. Is there a way to check for oscillation with a volt meter on this chassis ??

Resistances are given to the left of the schematic, which should make deciphering the various coils a fairly simple matter with your ohmmeter.

Regarding the oscillator, if it is functioning, there should be a negative voltage on G1 of the 2A7.
