I replaced transistor Q127 (a hard to find Fuji MOSFET) and two resistors, the only visually damaged parts. Plugged it in and turned it on, and it immeadeatly blew up with such violence that the dog ran out of the room and hid under furnature. Whatever is wrong needs a schematic to fix, and pioneers support has been worse than useless!!!! At work I was able to get a schematic for a piece of gear (satellite HPA) built in 1984, under a previous company owner. And they sent me PDF files, free. That is what I expect when I call service. Instead Pioneer replies, 2 days later, the manual is $49.99 and even if I wanted to pay for it, it was on indefinite back order anyway. Go choke on it pioneer, that's BS. I spent $8000 for this thing I expect a little more in the way of support. If Varian can produce a power supply schematic for a HPA from the early 1990s why is it so hard for you to get one? I don't believe for one minute they don't have the schematic saved on some computer, big companies don't just delete that stuff when they stop making it.
