Faulty Roland LAPC-I

Postby suntac » 2019-1-08 @ 17:26

A friend of mine recently bought an old Roland LAPC-I card and asked me to repair it for him. The right channel is much noisier than the left one. I believe I can fix that, but there is another problem. The card usually starts sounding quite weird and distorted (digitally) after a few minutes, 5 or so. Sometimes it may work fine for an hour or even longer.

I got some ideas from the MT-32 Services Notes, but the LAPC-I Services Notes would be much more helpful. Does anyone have it and is willing to share it? We would gladly pay for it, if necessary.
