VINTAGE VIBE WURLY AMP INSTALLATION INSTRUCTIONS
Models 200/200A and Chopped Consoles
1. Ensure that the piano is unplugged from the wall outlet and that all voltage has
been drained from the stock amplifier. Remove electronics rail from piano.
*For 200A pianos, save the screw that secured the AC inlet “earth ground” wire
to the rail as you will need to re-install this at the end of the installation.
2. Detach power transformer secondary wires (blue, red, red, red/yellow) from stock
amplifier PCB. If clipping, do so close to PCB.
*For 200A models, the green ground wire connecting the stock amplifier PCB to
the rail will not be utilized in the new installation.
3. Desolder wires from Volume Potentiometer lugs 1, 2 and 3.
BEFORE:
AFTER:
*If there is a jumper between the potentiometer shell and lug 1, remove it.
