The Electronic Organ Servicing Guide ( Sams 1971) is a 128 page large softbound book that is available at Amazon used. Written by Robert G. Middleton, it's very thorough and has plenty of drawings. It's also far more practical for troubleshooting and repairing than just about any manufactures service info. Your organs schematic and this book can help you fix almost any organ problem. Was recommended by a guy who was shocked when he paid $25 for two old xerox copies of a Thomas organ schematic.
Is that square silver colored thing on the wall of the housing a selenium bridge rectifier? A lot of people recommend replacing selenium diodes with silicon diodes (along with a series resistor).
Hi! I have recently bought a Farfisa Matador 80... It works perfectly except for the volume pedal. As you may know Farfisas Volmue Pedals are optical, they doesnt use pots. I have just disassembled the pedal and I cant find the problem... the light bulb is working perfectly. As far as I can see, as the Photocell receives less light the volume should increase and vice versa. I suspect that the problem comes from either the Photocell, or the organ itself. What do you think??
What about the ceramic resistor? I've had to replace several in a Lowery due to noise, hum etc. I know this an old video. I'm looking for a schematic for a Farfisa FAST 4.
