Will anyone help me to get the main relay RL2 to opperate correctly?
I've put 5 hrs into this amp so far and have the filament, the 12V circuit, and the B+ all up and running well.
However, when I flip the switch from stdby to ready, not only do I get the B+ going but also the RL2 energizes, the points move over to the other side, and the amp is immediately put in transmitt mode with the receive cut off.
Can someone help me with a procedure to stop this relay from energizing before the mic is keyed? I checked the 4 transistors nearby (TR3, 4, 6, and 7on the version 4.00 schematic) for shorts and came up with nothing there.
Thanks for any help. I really want to hear this amp sing again.
