Hello Tom,
The way I blew one of mine was due to a very tiny fragment of metal
shaving
getting installed along with the heat transfer pad of Q7, I took only a very
short time to let the smoke out.
This happened quite some time back, so I can't remember what I was
doing or
trying to accomplish, but I'd say if you've done anything to Q7/Q8 and can't
find the short to ground. It "might" be something like what I did. Believe
me it was a tiny, tiny fragment, but when Q7 was tightened down it made
contact and did its damage.
Just a bit of my experience that you can check and maybe gain from.
73,
Terry KA9TXE
