Schematic of Acoustic B200H needed

[gwbrandt]

Originally the output module blew out & was replaced. It worked well for a while, but later it developed a problem with the output relay switching on & off with signal and load connected. Output swing is fine w/o a load. I do not see any DC offset or oscillations on the output so need to see what the relay circuit is sensing.
Acoustic ignores my emails & I cannot get a phone number for them.
Thanks for any help to find a schematic or resolve the issue.

Does anyone know how to get in touch with acoustic. They do not have a listed phone number anywhere that I can find and they do not answer any of my many emails.
Thanks
