Discussion about the Korg PolySix synthesizer

Hi, everyone.

I as many other picked up on of the replacement pcb's and have been waiting to see if all the errors on the pcb have been narrowed down, i guess the real question has anyone succesfully replaced the original pcb with the new one yet?

sorry if this question has been bashed to death...

Well...Andy and I have...

I don't think I've gotten a report from anyone else.

Hi,

I have 8 on the go right now. I have 4 which are complete, calibrated and
working. I can tell you that if you build the board, apply the mods to both
R98 and R51 you will have a fully functional board. BTW the new boards for
old and other help is available on request. Just send me a private message
if you are really stuck.

Cheers,
Andy

When I get my new board (the prototype!) I will pop in my unit, power on and go through the paces...and report back to the list

Its been a sec since I have looked at the service manual but should I do the 56k reset thing and adjust the leds?

From my understanding the boards are already calibrated and should simply go in, power on and load the factory (or whatever) presets? 

Thanks again I am anxious to see my p6 come alive!

I built mine within a few days of receiving it, installed it, and did the calibration.

It seemed to work fine when I played with it, but the p6 is presently on the shelf not being used because I've been playing with other toys the last few weeks.  :)

I'll pull out the p6 this weekend and see if all is well.

Much thanks again to Andrew and Jed!

Yea please do put it thorough its paces!  I like to boot up mine the night before and let it heat up for 12 hours before messing around but not sure if that is a silly idea or not ( I know with the 106 its good idea too).

Any one have a bomb patch list link as well? =)

Hi,

There are four areas of calibration you MUST attend to after building the
board. Because the trimmer are off the shelf from the factory, I doubt very
much if they will be set right. About 30 minutes is usually all that is
required for the circuitry to come up to operating temperature. Make it an
hour if you are conservative. 12 hours is probably not necessary!

1. Adjust the init clear (reset)
2. Adjust the d/a convert offset and current limit
3. Adjust the MG gain and frequency
4. Adjust the PWM/PW gain and frequency.

The instructions to do this are detailed clearly in the first section of the
service manual. Your new 367 will not be at all satisfactory if you don¹t
bother. You might also like to verify that the power supply is adjusted
correctly and each of the rails are in tolerance. However, if you read the
calibration procedure in the service manual it will remind you to do this!

Cheers,
Andy
