ARP 2600 VCO, based on 4027-1 ’VCO-2’, oscillator sync, buffers, precision reference voltage.
The Steffcorp 2600 VCO is an analogue oscillator with full voltage control based on the 4027-1 ’VCO-2’ oscillator used in the ARP 2600. It’s not just a copy however, we have gone to great lengths to bring it into the 21th century.
A much needed precision reference voltage was added, as well as buffers and a few other goodies.
Going SMT offered the means of improving the PCB-layout even further, as well as a selection of easy-to-source parts. No more treasure hunts and extravaganza prices.
On top of this, a good bit of time was spent on analyzing and comparing modern parts to find the best matches of the original part specifications.
