Larry, the same thing happend to my Omni VI.....went back 3 times to have
both the finals and final driver transistors replaced. In my case, I was
running the rig and another hf rig at the same time on a common power
supply...on different bands and different antennas. The last time the rig
went back to TT, they only had to replace the driver transistors...which one
can do very easily.
Right now, I am running separate power supplies, Ten Tec model 961, one per
hf rig....otherwise same antenna tuners and same antennas as before. So far,
fingers crossed.
I will never be too sure what caused the finals to blow...but I think that
rf was getting into the final brick via the power supply positive lead.
As for a bullet proof cure??

OK, guys, I normally consider myself a pretty patient guy. But this is
getting to be a bit much.
I have sent my OmniVI Plus back to the factory 3 times in one year. Each
time for (roughly) the same problem: the transmitter keeps blowing out.
After the second time, I set myself up with the best antenna tuners that
money can buy, just in case it was my fault. As of now, I really don't
think it was.
Each time, I am able to operate for a short time, a few hours, before
something gives, and the transmitter is then only able to go into some
kind of oscillation where it pegs the current meter after advancing the
power level up past a couple of watts. This happens while slowly and
carefully advancing the power control in preparation for tuning up.
It happened again today. This time around, I was able to run 80m during
sweepstakes a few weeks ago for several hours, and that is the only time
I have had the radio on since getting it back. Then I tried to tune up
on 20m this morning, and <poof>.
To their credit, they have replaced many components, last time at no
charge. But this will be the second DX season that I have missed due to
the average 4 to 6-week turnaround on repairs - (had to use my spare
Yaesu rig for cqww, ugh.)
I really like Ten-Tec equipment, but I am rapidly losing faith. It is as
if they are just putting band-aids on the problem, instead of actually
fixing what is wrong. I have heard, for example, that certain parts for
the Omni's are simply unavailable, is there any truth to that?
I would really hate to become one of the rice-burner users, but what is
my alternative? Any others with similar experiences? Any suggestions
appreciated, thanks.
