![]() No manuals for the Micro90pv, and no affordable repairs. I was stunned that Boston Acoustics has incredible quality when it looks like a piece of crap from China. I can only afford to spend $99 on this repair. He is in assisted living, and can't have a malfunction sub, or he may get kicked out for disturbing his fellow room mates. I'm trying to fix this for my 85 year old grandfather. If you don't have a board, OR a switch that I can solder on, then what are the specs of the switch. It has four leads, and its four leads are 90 degree. I referring to the board with the toggle switches for power, and polarity, and the board has the volume control and inputs on it. So INSTEAD of wasting $280 on a new cheaply made amp that will fail i 6 months, how much is a new upper board. So I desoldered it, and now its in a million pieces, so i threw it out. While trying to fix it my self, because you hid the glue with black rubbery crap, the power switch broke. What? a new amp for $280 cheaply made with black crap and glue? Are you serious? Anyways, it makes random noises at times. You guys used glue and screws? GLUE in a 1K Surround system? Then you put rubber black crap over that? Wow. Can someone help? Also, is there a repair manual for the Boston Acoustics Micro90pv? I looked at Parts express, Radio shack, and no luck. Both switches look the same, except the Polarity switch has two positions, 0 and 180. I have included pictures so you can see the solder holes, and the switch next to it. (When I say three way, I mean the switch has three positions. It has four leads on it and is at a 90 degree angle. Trying to remove the boards, I broke the power switch. The black crap you see in the included pictures are the rubbery epoxy. Then they use a rubbery epoxy (feels like silicone) over that. Glue to secure the boards to the metal plate is everywhere. Its amazing how they want $287 for a NEW amp, when they make it so cheaply. I'm attempting to repair a BA Micro90pv amp. ![]()
