Korg Mono/Poly

Hi there Danjel!
 
I had the same problem as you with the tuning of OSC 3. But while trying
to tune it i burnt the whole PSU. 
I wonder, when i have repaired it:
 
Where you able to tune it without detaching the Osc board?
 
"The chart on page 1 shows the order of trimpots to tune for the VCO1
is:
VR102
VR103
VR101
VR104
 
but then on the next page it shows the order as this:
VR102
VR103
VR104
VR101
 
Which one do I follow??"
 
Wich of these was the correct one?
 
Best Regards 
Alexander Henriksson

(Seems as Osc3 is the weak part of the MP4.)

So I finally figured out the stretch tuning system. I have to say that
the manual was terrible in explaining what needed to be done and it
was only from looking carefully at the schematic that I could figure
it out.

VR2 controls the voltage for OSC1, VR1 controls the voltage for OSC2
etc.

The signal you are measuring is at the connector (reading from left to
right) pins 2, 4, 6, and 8 and it is relative to ground.

There is also a mistake in the calibration manual for the next part.

The chart on page 1 shows the order of trimpots to tune for the VCO1 is:
VR102
VR103
VR101
VR104

but then on the next page it shows the order as this:
VR102
VR103
VR104
VR101

Which one do I follow??
