Found the issue, and it is related to shorted HF finals. Boy, when these
things go, they really go. I would like to know how they wound up that way,
this was a "Tech Special" from flea bay. Good news is the finals are
available still, bad news is, they're $36 each.

Thanks,

Brian

Hello to everyone on the reflector. I just came across a 706mkii that's not
powering up. I opened it up and looked at the PA section, C82 and Q1 are
blown. My question is do you suspect a reverse polarity, bad finals, or a
just a plain cap failure. I'm hoping it's not a final issue which I still
need to desolder and test.



Just curious if anyone ever had the same failure.



Thanks,



Brian
