Steffcorp ARP2600 VCO MK2

Description:

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.
