Hey all,

Long time lurker here find alot of valuable information and it's awesome. Anyways, I am attempting to tune my Korg Trident MK1 and it's falling out of tune no matter what I'm doing. I think it has to do with the antilog section.

If you see here in this link: ... ent_21.GIF

I hook up my meter the way they say in KLM-301 first step.
-11V is conveniently exposed on a PCB plane that I solder a wire to and put positive lead on R57 facing towards the op amp. In step two it's nowhere near 6.00mV it's around 600mV. This is confusing becasue step 3-2 says also to play C3 and adjust VR-7 for 600mV. Really just hoping someone has tuned one of these before and can shed some light.
