A friend of mine has managed to get my synth working, there was a broken track on the board where I soldered the display trimmer. He drilled the board and made a connection with a wire, also, the 6N137 (I think that is the right No.) was blown, not sure how that happened?
Anyway, it will be back with me on Thursday, hopefully!
Only one issue left, I seem to have lost all the presets I made, further more, I only have 16 named patches, all the other patches are blanked all the way up to 80.
I think I may have blown the eprom (is that right?) What is the part number and where is it on the board please, I am going to replace it!
