Dear Gspencer,

Welcome to this forum.

Hopefully, you have managed to make out the output transformer in the circuit diagram. If, as yet, you have not, look for S19 and S20 in de top right corner. In the adjacent parts list this translates to part 25.510.39.0.

Problem solved? Hardly. Getting hold of this transformer is nigh impossible. However, the end stage of the 938A resembles the 834a's end stage, i.e. same output valve en transformer type. As it happens I have a loose 834a's loudspeaker with attached output transformer. I saved the set for a rainy day, but I'm tempted to seperate the two and grant you the output transformer for a non-excessive fee. The way the transformer is fixed to the loudspeaker in a 938A is different from that in a 834A, so you will have to find a work-around.
Interested?

Regards,

Hans

Plain enough?
