Discussion about the Korg PolySix synthesizer

Thank you for the reply and explanations Andy.

I feel uncomfortable with my stupid questions. I have no electronic skills but I'm very interested in all these things. I keep on reading articles or users comments on electronic matters but I'm quite sure I understand correctly only 10% of what is written. 

For instance before you and Jed came to rescue damaged KLM-367A owners, and as OldCrow had disappeared from the face of the earth, I planned to "clone" the board by myself.

I've used the schematics from OldCrow's website and I've ordered the service manual. It took me weeks and weeks to draw the double-sided board using Photoshop and to compare components datasheets to find replacement parts.

I'm quite sure it would have resulted in a non working board that could have potentialy harmed my P6. Sometimes passion and will are not enough... Electronics require strong theorical knowledge and practical skills. 

When I was working on my so-called project I've read, for instance that 4558 op-amps sound crappy, and that NE5532 or TL072 were much better ones. Without knowing what exactly these amplifiers are or how they work I tended to think it could improve the overall P6 sound if I would have changed them all...

In some ways I didn't really changed since I was a child when I used to open electronic devices to "see" how they worked...

Yours,

Ben
