Someonw on here awhile back posted about a mini they had with no Oscillator board.

Well here it is...

I was already planning on buying this and popping it inside my MidiMini, and thusly getting a proper Model D analogue chain

The tuning of this very old oscillator board is horrible.
Have fun,

Besides the aforementioned tuning being awful, you're going to have to figure out a way to add hard sync.

Regardless, MIDIMinis and MIDIMoogs don't have true Minimoog glide circuits and glide isn't contained on the VCO board.
It's on the one board in the MM that's made by SE and not Moog at all.

Anyways, this board will go for a lot.

They all seem to come out of the woodwork at the same time...creates more frenzy, interest and a higher price...you see that with alot of stuff on ebay. Well maybe I should list my old mini board from my 2XXX model D...the new boards were sure an improvement. I think I paid $200 retail for the new board back in 1980...

Rudy has a point, the all-discrete oscillator board installed in the first run of minimoogs does not hold its tuning very well. Despite that foible, it will sell for an insane price as there were only a few hundred of these made.

The 3046-based oscillator board that replaced it is marginally better. The tuning can be made much better with select replacement of opamps, improved biasing, and better power rail distribution. Two major contributers to minimoog tuning foibles were the high offset high tempco opamps (741s - yuk!) in the summing circuits and the inferior power distribution between the board and the tuning controls on the front panel. I design automated test systems for a living and have applied my experience to taming my 3046-based oscillator board. There were over 8000 minimoogs equipped with these.

The final oscillator board used the near-impossible-to-source ua726 but held their tuning the best. Very rare to see these on ebay as these are the ones in demand. A little over 2000 of these are out there.

Hi Van
I would be very interested in your old mini board if you were serious about selling it?
I am currently restoring a 2XXX and that is the oscillator board that I need!
PM me if you want to discuss it.
Kind regards
