I submitted a question a few days ago I thought was quite appropriate
for this group. I didn't cuss or anything or try to sell something, but
it didn't get in.

One more try. I have recently procured a Carver PM-600 amp.

1. There is a switch labelled "sequence" and I can't imagine what might
do. I have done a lot of googling, but nothing.

2. The power supply transformer (EU) buzzes. Can anyone steer me toward
finding a replacement? I have contacted service centers in both U.S.
and Germany, but got no reply.

Thanks,
