My power transformer was bad, and I had trouble finding a replacement by the Philco part number.
But I determined the specs and found a cross-match in one a fellow radio club member gave me.
I verified the specs through testing that transformer's resistance and voltage readings:
It is an RCA part with number 970445-1 printed on the case.
It matched the voltages of the Philco 32-7976 at 250-0-250 and 6.3v, and
even the bolt holes lined up without chassis modification.
Perhaps someone else wanting a transformer for a Philco 39-30 will find
this cross-match useful.
