Discussion about the Korg PolySix synthesizer

Andy,

367 -  The P6 is setup as shown in Fig 1 of the service manual.
I have complete both the P/S adjustment which was slightly off before. And step (1) of which I had an issue but was able to get the LEDS to go from just A and 1 to all of them lighting up using the 56k res and adjusting VR1. after removing the 56k just A and 1 remained on. I did have some wrong components installed original including R2 which is now correct and original part from old board. I just did a test with my DVM and in a previous post you stated that the voltage should be 3.9v with the 56k in place. I am registering a 4.6v on the right side of R2.

369 - yes it is a lone blue wire. So was the cut trace between D1 and J2 intentional? If so where does the lone  blue wire terminate? I understand it should be along the +5v rail just was trying to locate where it was soldered to before it came loose.

Thanks in advance!
Daniel
