Howdy... Now you are doing something that my electronics instructor would jump on ANY student about...that 3 word word. ASS-U-ME. Check the fuses for an open, as they can develop a microfracture that is not apparent to the human eye. I have seen it before.

The Amp output section seems to be missing a voltage. Might just be a fuse device,...but, all visable fuses are OK. I have the + 41 volts, the + 28 volts, and the + 20 volts from my power supply. I also have the + 5 volts, and the +12 volt sources, on the Amp board. The highest voltage on the Amp output ICs (7301 & 7302) is only about + 5 volts. Seems like there should be some higher voltages on these chips. I don't think that the outputs themself are blown. There are seperate outputs for the left, and right channels. Can someone give me the voltage readings on one of the outputs ? or,...can someone provide a Pdf schematic of the output stages ? Any help is appreciated, LLW LeRoy Westlund Westlund TV & Electronics " It's such a pretty world 93 North Main today !.... Centerfield, UT 84622-0087 Look at the Sunshine.
