I am original owner of a TR4C. I leave the power switch on. I have the
TR4C plugged into a surge suppresser and use the switch on the surge
suppressor to turn the TR4C on and off. An old friend of mine that
worked at Drake, told me to do that many years ago.

Today I took my two T-4XB's off the shelf after way too long and
found that both of them have trouble with the power switch ganged
with the "gain" control. Nothing happened when i turned them on (yes
I used a variac at low voltage and i will recap the AC-4). Checking
with an ohmmeter later I found that both power switches were open,
but repeatedly cycling them brought them back. Is there an
established way to make them reliable?
