In step 14, the trimmer would be VR14, which is associated with the DAC.
The old KLM-366 does not seem to have this trimmer.

A couple of questions, regarding the instructions in TUNINGPROC.TXT. It is under Files, Mods&Repair folder:

- I have OLD version, no VR2, no VR15. How should I interpret instructions? 

- In the step 14) there is a "trimmer". Which trimmer? (The same mystery is in the original Korg Repair Manual. There they are talking about "confirming"... not clear at all.)

- I am using another, very precise digital synth as my tuning reference. By listening to beats, I can be very accurate. This instruction requires precise voltmeter and voltage calculations. Is it not much simpler to use ear instead of voltmeter? Can anyone suggest tuning procedure by ear? Or at least by a good guitar tuner? 

Thanx!
