      Oh man thank you Jazz! Got a weird preamp issue and hope this will help me get it sorted.

        Those schematics are, unfortunately, incomplete.

        They only include PA driver, PA power section and LED board driver.

        No power supply schematics, no preamp schematics, only those three.

          I took that to be an RCA connector at the input of the driver board? And level control at U101?
          It's just a power amp for line level signals, isn't it?

            That is a bummer. I will be able to get it all apart this weekend and see what is happening but not sure without a good schematic.

              So this is a bass amp, not just a power amp, and the preamp schematic is missing. There was another thread about it and the schematic was never found.
              I believe it used to be here, maybe wayback machine would have it? cerwin-bg250-1.jpg Photo by monolith | Photobucket

                That's the LED board.

                  That's odd. Now there are 2 pics of the LED board. Earlier when I linked it, one of them said "picture removed" but its tab was labelled "BGW 250 Preamp".

                    If you click on the link in the first post here, you'll see what I mean. The photo name in the address bar will actually change after a few secs. Weird.

                        I did see that when I was hunting as well. I hope it doesn't come to that but $20 isn't a deal breaker if so.

                          If possible, post it here after you get it.
