[Yaesu] QUADRA-REPAIRED

[N8NN]

Bob -- You are correct! and very helpful...  After changing the remote
switch, the amp started normally.  The Quadra is working normally now.

I would appreciate more info on the resistor you replaced and the capacitor
you added.  If it fails again, perhaps I can make the repair myself.  Does
it require much disassembly to reach the resistor.  Disassembling the thing
always seems to be the hardest part.
