This is NOT a binaries nesgroup. This should have been posted on news:alt.binaries.schematics.electronic or even news:alt.binaries.pictures.radio if you want people to see it.

Not just this newsgroup. You should only post binaries to groups with binaries in their name because most Usenet servers will drop the message, or at least strip off the attachment.

Good for you. Not all news servers will accept a binary file in a non binary group, so you get poor propagation. The person with the answer to your questions may never see your message that way.

Any ideas or recommendations of what should be done with this piece of equipment?

I assume the troubleshooting has been done with the pre isolated from the power amp section?

What's the voltage on the terminals of Q605 and Q607?
