No suggestions so far about resistor values.
Well, I thought that the worst thing that could happen would be, that
the P6 still scaled strangely. So I replaced the PC-1 with my VTL5C1,
and replaced R93 with a 1k2. After all, the LED side would probably work
the same.
And guess what. It works perfectly. So the scaling issue is now solved
with a new VTL5C1 opto-coupler.
And while I was at is, I thought that I might as well try the brightness
mod, and remove the effects VCF-chip, and it sounds great.
