"This is the Oscillator annd Nosie section from the *final* prototype #10 of the micromac. The pervious design was excellent but I had to cut one or two track and hand wire them. Now it is perfect and ready for test/production.
Also to be noted here- for the Desktop unit- the supply is now on board with an AC/AC adaptor firing power up. Ultimately- I considered the idea of using a switched mose supply- but the supply it's self was over half the size of the mac! So I designed the linear supply that you can see on the rear view, bottom right. Plenty of trim pots too as you can see. By tommorow- the VCF, VCA, Envelope Generators and the hands on control board will be built and match up to this circuit!"
