[sdiy] [AH] SH-101 VCA DC offset trimmer?

[Altitude]

It's a trimmer and a resistor that connects to pin 2 of the BA662A
(R201)This is the same trick used to adjust the DC offset on the x0xb0x with
the BA6110.  I use a 10M resistor and a 50KB Pot (thanks to B Castro).
Works really well, you can get the "pop" down to nothing

It looks like Roland just went with "offset selected" op amps and never
populated the trimmer

So for some reason Roland didn't include a VCA offset adjustment trimmer in
the SH-101. There is a location for one on the PCB though -

When replacing the BA662A VCA it would be nice to have that adjustment.
Anyone 
ever try installing a 100K or so trimmer there? Looks like the proper traces
are 
going to it...
