Re: [vintagesynthrepair] E-mu pk-6 synth with bad data entry control knob

2008-01-02 by Mike de Vries

I'm not too sure if you have the same problem that my EMU 6400 Ultra had, but the encoder in mine went a bit like that.. If i spun it left, it would often go right!
there is notes on fixing this, but basically, get 2x 1uf electrolytic caps and solder them between the encoder and ground. (A LPF filter to eleminate noise)
I did this to my Emu and it worked brilliantly.
Here is the link.

Good luck!

sometimes scrolls backwards, and often, does nothing at all.

Does anyone here know if this is a major repair job? I know that e-mu
doesn't make synths anymore.
