If it isn't doing it on any other band, I'd say he has either a loose
connection in the 10m LPF circuit or a bandswitch contact burned on that
band.
If it does it on other bands, there are other possibilities, e.g. ALC
diodes.

Subject: [TenTec] Triton IV shutting down TT 262G Power Supply
My Father Don VE3IYA says that his Triton IV that was working w/ low
output
on 10M is now not working in TX. As soon as you hit PTT in SSB, the key
in
CW or go to LOCK mode it shuts the TT 262G down. After a few seconds and
a
power cycle on the 262G it will come back to receive. This happens
regardless of drive setting and YES it is into a known good dummy load.
We have not had the covers off yet but I suspect the 80284 SWR ALC board
will need to be looked at as well as the 80276 Final Amp and the 80280
Control Board. So what do the experts on here say? We are just thinking
out
loud before diving in.
