Thanks for those very helpful links. I was able to measure 52 ohms (out of
circuit) from the red to the yellow wire of the output transformer. That
would not seem to be agreeable with the schematic which puts the red on
the
primary side and the yellow on the secondary. Looks like the output
transformer is bad.



** No way is that reading correct.

You must have confused yellow and brown leads.

A short from primary to secondary on the OT would no allow the amp to
operate at all - the supply fuse would blow.
