Hello everyone, While restoring and old lowrey organ i must have touched something in this board and now this is what i get. I been looking at it for a couple hours and dont know what could be causing it. This section worked allright before i unscrew the board, now i get this uncanny noise mixed with the notes or nothing at all. Has anybody worked on one of these or simmilar? Have a great day thanks.
