Question about Amplifiers & Preamps
Just to let you know that FixYa has sent the diagram of the A-8190 and that am checking possibilities. Let you know ASAP.
I don't have the info on the initial question/posting, but Onkyo systems I have worked on often have open driver transistors as well as shorted outputs. With one of the driver transistors open, the voltages tend to float to one side. The 18V you mention sounds like that is what is happening. have the initial asker replace the driver transistors (as a pair) just like the outputs.
Keep me posted.
