Ok guys, I need help. I picked up a 9800 that has an output issue, very little output. I took it to a local tech, and he has had it for two months now, and he says the cause of the issue "escapes him" ...ugh... He says it is showing excessive voltage on the output section, he says there should be no voltage, but he is showing something like 70 volts on the output side? I am going to go pick the unit up as I now have no confidence in his diagnostic abilities. does anyone here want to jump in this one? I really want this thing fixed, or i may just sell it as a parts unit?
