Well, I know Bose equipment can be quite unconventional, so anything I say
may not apply, but in general:

Volume full blast would usually be caused by a lifted ground or a defective
volume control, sometimes bad solder connections.

Not quite sure what you mean by not driving an amp properly. I assume you've
checked the amp and it's OK?

Sounds like perhaps the easiest thing would be to repair the receiver.
What's it doing wrong?

Mark Z.

Mark, the volume in one room is wide open and the line out for the
independent amplifiers was driving only one channel properly.

The project was initially started to verify that the in wall wiring
was not the source of the problem. Along the way I realized the
circuit boards traces resemble an Apple II. Almost no one repairs
other types of electronic gear anymore. And with electronic
technology racing along at light speed it seemed prudent and maybe
cost effective to replace the receiver with newer more modern
receiver. Additionally the receiver had been repaired shortly before
I moved and also exchanged about a year and a half later.

Replacing the receiver seemed to be the most logical approach.

Thanks.

Bose receiver broken and need replacement or knowledge or a
recommendation.

I have a very old Bose DEMC-2-B receiver that has stopped working.
Judging by the size of the traces on the printed circuit board it is
early 1980's technology and I am looking for a replacement. The basic
setup is three rooms with two Bose 102 ceiling mounted speakers and
remote volume in each room. The best that I can tell there are three
amplifiers in the receiver along with an AM/FM radio.

Other rooms are connected but they have independent amplifiers and
work properly when connected to another source for testing.

The most knowledgeable local audio store person that could be found
advised that Bose was different and suggested only a Bose receiver
could drive the speakers. Somehow the 'only Bose' comment did not
test for reasonableness.

The system is in a home purchased three years ago. The receiver has
been removed and the hole in the wall is being repaired. The wiring
is accessible to the new receiver location with only minor changes.
Since the unit is broken additional features are not the primary
consideration. Also there is no interest in replacing the speakers,
which sound fine for my purposes. Hopefully the receiver can be
replaced with current technology without replacing speakers or
rewiring the house. I am simply trying to solve the 'it's broken
problem'.

Thanks in advance for any insight that can be offered.
