If the relay is "sticking," the problem is a
bad 6EV7 vox control tube. It's a common problem
with TR-4s.

This rig has a relay problem, but otherwise seems to work OK. Output on
SSB will whistle up to around 200 Watts. But I just don't have time to
fiddle with it. Power supply included. As for cosmetics, this vintage
rig is easily an 8+. Will incl. D104 mic wired for the rig if we hold
to $250 + shipping for all.

Thanks,
