Hello, I just purchased a set-up that includes a BP-25 and 4B-ST power amp. I am not able to get any sound from the right channel and after doing some isolation tests, I am pretty sure it is the output on the pre-amp that is at fault. One thing I noticed, is if I turn the balance completely to the right so I hear nothing, and then start cranking up the volume, when I get to a reasonable high volume, the right channel suddenly activates (at the right volume) but when I turn it back down, I lose the channel again. Has anyone experience this problem before and/or can anyone suggest a solution? The source is a Linn Ikemi CD Player and I am positive both speakers are working fine. -Matt
Feed the amp with the left channel preamp to the right channel input on amp and check output. If you get output from amp then pre amp nedds to be checked out if still no output then amp is suspect. Randy
