I have a HEC M200E, 3 tube. Preamp works, but there is no key. Thing I could swap out the transistors on the back, and see if it keys? Maybe a bad relay?
 

Moved all the transformers around, mainly to see if I would loose the receive amp portion, I still have it and the amp isn't keying. So, time to try and check the relay. Old schematics suck:headbang
