Thanks for that information. It would appear from the output transformer parts list that the transformer that was originally on the speaker is #32-7968. Year would be 1939. Goes with a push-pull output using two 41 (6k6GT) tubes. A closer examination of the very small print schematic indicates that the speaker is a PM type. The ratio specs for the transformer is 16,000 and 1.25. I assume that this is for the primary and secondary windings. Does this seem reasonable?
