Hi everyone -
I just recently completed the Stereomour II kit, went through all the voltage checks and resistance checks and everything worked great...for about a day. Then, when I fired it up on day 2 - the left channel gave a weird buzzing-whooping-humming sound that was not constant, and did not output hardly any volume at all (I could still - barely - hear the music). I unplugged the speakers, flipped the kit over, checked a few things, re-soldered more joints than I care to admit, but I am still left with one anomaly - when I do the voltage check, I get a voltage of something like 99-105 DVC out of terminal 7, instead of the normal 170-230 VDC to be expected. For comparison, I get something like 180-190 VDC out of terminal 14, which is the mirrored terminal and is of normal range. All the resistance checks are more or less normal.
Despite my better judgement I fired up the amp anyway - and for a moment, both channels seemed to work fine; however, whenever I bumped the desk the amp was sitting, I would get a momentary strong static out of the left channel. I then gave it a few minor disturbances - walking on the floor, dropping books on the desk, etc, and each time I would get a strong static out of the left channel only.
I have almost zero electrical experience and have been staring at the backside of this amp for hours, so any help or advice you could offer would be greatly appreciated. Thanks so much in advance!
