Roland Juno 106 chorus input+ speed mod and repair
This one was suffering from juno cancer on one voice. Uncoating the 80017 chip did partially not work (no resonance). Put a replacement chip on a socket and recalibrated all of the 6 voices. Took 3h Mods: 350€ + parts + postage (No VAT (small business §19 (1) UStG)) For the chorus there was used a test-point on the board as input and a new pot was installed for chorus speed. Very useful! 1-2h
