Chris-
Rich was, I believe, following up on a query from me, as I've recently picked up an MTR-15 in NJ.
I was able to get a PDF of the operators manual from Aheadtek, but they don't have schematics/PCB layouts.
If you have schematics I'd be interested in borrowing to have them scanned. Would that be possible?
Alternatively, I'll gladly pay all costs associated with having them scanned at your end - I'd like to make it as little trouble for you as possible.
Thanks vey much,
Mike
