Roland System 100m

there´s a trimpot on the psu board that sets the +/- 15 v,
or else the psu may need a recapping :

Subject: [RolandSystem100m] Osc tuning & power supply..?


Excuse my lack of technical knowledge (musician rather than technician) but can anyone
explain to me why my oscillators track & tune nicely in one of my 191j's but not if I move
those modules to another 191j?

In the second 191j as you change the footage on the oscillators it doesn't track equally up
the octaves (i.e. sounds out of tune).

At first I thought the oscillators must need re-calibrating, but then I checked them by
moving them to the other cabinet an they work fine in that one...??

Unfortunately the cabinet where they track nicely in tune has an awful hum/buzz from the
power supply - hence my wanting to use the other one.
