[sdiy] Jupiter 6 filter resistor values

[Tom Wiltshire]

Hi all,

I've been looking at the Jupiter 6 filter, an interesting dual 2-pole  
SVF design. It's based on Roland's IR3109 quad transconductance amp  
chip, but that needn't stop us, since there are other OTAs out there.

However, many of the resistors in the circuit are part of resistor  
arrays for which only (apparently) unhelpful part numbers are available.

Does anyone know what values the following are? Has anyone measured  
them?

RA11A-D, RA14AB, RA14CD: RM0891
RA12A-D: RM0690
RA13A-D: RM0688

The relevant schematic is page 33 of the service manual if you've got  
it, otherwise:
