With any luck, you won't have to clean the contacts again for a
couple of years.

Well , back to the tubes...
The tr4c is fine till fully warmed than the problem comes back.

Recap;
After TX (cw) when relay releases, the RX sounds some times muted but
still there, the S-meter will rise up the scale to about 40+ and the
rx freq is off a bit (like on the wrong sideband)
If I re-Key, all will return to normal...this problem will happen
about 50% of the time... looks like relay is fine), but more like the
mute curcuit is hanging...???

Relay cleaned but problem pops up when fully warmed up after 20+ mins,
I'm going to pick up a new vox curcuit tube (6fq7) and replace to
eliminate that... will post results.
