Finally took it home today! And then brought my other machine in for alignment.
So many weird problems...I'm sorry if I'm skimp on technical details, I'm going to request a some documented specifics, but...
He rebrushed the motors. One of them still doesn't work, runs backwards and draws too much current, so I ordered a replacement motor and he rebrushed that one and installed it.
***does anyone have any experience with fixing a backwards running motor or is it trash?
A couple meters weren't working right in various modes. Bad voltage regulator.
A few boards weren't biasing right, it ended up being the trimmer pots were bad!
I think either an audio board or bias board was bad.
Some other stuff too, can't think of it all at the moment. But I had him align the machine and am getting ready to install in my new studio.
I didn't want to leave this thread open ended because that shit drives me crazy. This machine ended up being a bigger problem than any of my other 388s haha but I love them so consider this another machine saved from the landfill.
