Hi there, I picked up a farfisa mini compact today and it is physically in great condition. It sounds great too--with the exception of all of the D notes. A sound is produced when I hit the note but very dischordant and rapidly pulsating.
I am pretty sure I shouldn't do this but I pulled the oscillator card and after doing some initial examinations, I fired up the organ. If I run my fingers along the back of the pcb card while playing a D, I can get the note to sound appropriately if I touch certain spots. I have to be making contact in more than one spot. Sometimes the note will be reproducable after stop making contact with the card. If I continually run my fingers along the back of the card, it will cycle through a whacky series of tones.
Hopefully someone can help me figure out how to proceed.
Thanks.

Hi
I have exactly the same problem with the C's on my compact deluxe ; when I "touch" the second row of dividers/caps, the "pulsating" sound is gone
all the Cs are well divided even thou the sound is dirty, so I think all the germanium transistors are in good shape
as the resistors are rarely unfunctionnalI, will change the caps only, and will keep you informed...
cheers F.

Just thought I would update. I changed a single transistor in the oscillator section of the card and it did the trick.
