Minimoog D pitch wheel modification

Hi,
I have a Minimoog D with the old oscillator board.
I would like to do the deadband pitch wheel modification.
I am unable to find the complete instructions for this or the service bullitin #830.
Do anyone have this?

What does it actually do, please?

It simply adds a little dead band on the pitch wheel. The mechanic wheel middle detent is not keeping the pitch at exact zero.

Hi Till,

So is it for the purposes of a repair, rather than a sophisticated modification?

It is both.
For those experience problems with the pitchwheel not centred perfect at zero.
And those with the fear it might not center perfect in the future.

Hi Till,

Many thanks.

Is it a problem which only occurs in the very early 'Model D' Minis?
