checking the amp is in good condition throughout. The source, outputs, etc all be fine but stops when connecting the amplifier LM317 regulator protects and warms

What can be the cause?

* some integrated circuit will be damaged?

I'm working on one of these amp right now. I'm having similar issues as described in the first post.

SeanKane, do you have the schematic for the pre-amp board? I contacted RF, but they could find only the schematic for the rest of the amplifier (not the pre-amp)

lmk & Thanks

I'll look but I don't think so, Usually if you replace the op-amps on the board that will cure your problems, if they are like my original post problems.
