STEFFCORP - 2600 VCO

Hey peeps,
I figured we could use a thread for any builders of the new VCO from us.




Here is some text and links!

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.

Thanks for reading!

Nice, everything looks pretty easy going too! The hardest parts being Q1 with the small pitch and the electrolytic smd. But they're still easy enough.

Hey steffensen,

do you have some THT pcbs left?
I still have some rare parts left which i would like to bring into one or two additional 2600 VCOs!

Yes, super easy build actually! Even Q1 is easy with some flux.
Same goes with the electros imo. But i might just been lucky thus far. razz

No THT left. It's all SMT now.
Once i gave it a go i realized how fast and easy it was!
That said, i might release the older THT designs in some version in the future.

If needed I can preassemble the ICs and Q1

Just ordered my parts - looking forward to this
