Discussion about the Korg PolySix synthesizer

Because these dont wanna work very well , I started double checking res values. One place that's weirding me out is across R77. Old boards measure about 40 K ohms ( with other components in circuit) . The new boards measure about 180K ohms ( the value of R77 alone)

I've built 3 and at this point it would have been easier to rework the originals.  30 yrs in electronics engineering and test and I'm not happy with these AT ALL

So we'll be seeing your own offering soon? I have constructed well over 30 of these and only a small handful have caused any real issues. In fact I can almost stuff one without referring to the diagrams. Believe me, they do working if you solder them to together properly. However, I do agree with you on one point. The board do take a long time to assemble and in marginal cases it is simply quicker to run a repair as you have found. I would only consider a clone in the case of severe battery damage.

Bye,
Andy

Hi Scott,

I'm sorry that these aren't working out for you. I am a bit surprised to
hear you find that they are not working very well. There are over 400 of
these boards out in the world now and, in my recollection, we haven't heard
any complaints that haven't been able to be resolved. There have been
plenty of user errors along the way, of course, and there are known bugs
posted on my website.

You have far more experience in electronics than I do. If you feel this is
a faulty product I can refund your money. Your time, of course, is beyond
my ability to refund.

As Andy mentioned, these take a long time. There are over 1200 solder
points. No way around that unless you redesign the board, which is not what
we set out to do. But in cases of extreme battery leakage (like my own,
which resulted in the creation of these boards) they are the best
alternative I know about.

If you would like a refund, please contact me via email.

Best regards, and my regrets that you are disappointed with the results so
far.

Jed Jorgensen
