PG-380 schematic

2015-06-21 by sneakyflute@...

Hi.


Does anyone have the schematic pages for the PG-380 midi guitar? I have a dead trigger (after a full recap) for one string. But the scans for the schematic pages are all missing from the PDFs that are available online.


I need to know where the negative lead from C36 on the trigger board (board MA3M) is supposed to connect. I would guess it is supposed to have a lead that connects to ground, but it really does not look like there ever was an actual connection on my board (though, it is possible that the traces were corroded away by leaky capacitor gunk).


I also need to know where the test pads are for the calibration procedure (supposedly indicated on pages 2 and 3 - the missing pages).


Thanks very much - DT
