Pete: The relay to key the amp is set on one of the menus BUT you metioned you
have the softkey
in the amp so you really do not need to "reset" the keying relay.
I agree with the idea of pulling each board connector and reseating them.
You have a good source of help at TenTec and they are always ready to assist.
Try the reseating
and then call the service dept tomorrow for the expert info.

Pete,
the first line of troubleshooting this project would be to pop the top and
bottom, watch out for that speaker wire, and then one at a time pull and reset
each and every one of the MTA (mass termination assemblies) ---those white
connectors with the wire wires---
do that on each one and several times.
there can be oxide that builds up on the pin and by exercising the connections,
you'll fix a lot of problems.
I'm not saying that will smash your bugs, but it's a good place to start.
do every connection going to the logic board and the front panel.
