Some time back I started designing a series of small (2" x 2" PCB)
mini synth modules ("MSM"). I got as far as designing a sawtooth VCO
and a CA3046-based Gilbert cell VCA, having 2 each of the PCBs made
for them (double-sided, through hole plated, tinned), building up one
of the VCO boards and having a 3U-high (Doepfer-like) Schaeffer panel
made for it, and a start on one of the VCA boards.
The original (archived) webpage is here:

At the time I got the VCO to function over about 10 octaves (from
memory).
But I simply don't have time to continue these modules with all the
other synth projects I have lined up. One notable result of this
"clearing of the decks" was the completion of the 18dB state-variable
filter board released a couple of months back.
So I'm offering for sale all of these parts, including some other
components, as one single package comprising:
- four PCBs (2 x VCO, 2 x VCA)
- one 3U-high Schaeffer VCO front panel
- four unused new-in-bag 2SC1583 NPN-pair transistors
- four 3000ppm/C temp.coeff resistors in surface-mount package (was
Farnell code 732-369, now 117-4311)
I'll include all the documentation files I have (mainly PDFs of the
schematics) on a CD as well.
All this for £50.00 or nearest offer, plus postage. I am happy to
ship internationally. I take Paypal for non-UK payment.
Email off-list if you're interested.
Cheers,
Neil
