    Hallo!
    I have searched for the tlc555cp on mouser and other stores , on the bill of materials, there is standing that ic2 has 14 pins, but the tlc555cp have only 4 ?? is the tlc555 the right one ?

    Hello, sorry, we had an updated BOM but it never loaded correctly. It’s correct now; the part number is 595-NE556N.

    What is the purpose of the 78L05Z Voltage Regulator? The APC kit doesn’t have this part.

  5. Steve Harmon says:

    Hi Greg, the designer brought this circuit down to 5V for better performance in modular for the CV inputs. The IC’s will run off 9V as well. Just a little bit of clean up. Thank you for your question.

    You have an idea for a good alternative for the Bourns 500k pots? They are hard too find at this moment and I have 2 APC’s coming my way from Thonk…

  7. Steve Harmon says:

    Hi Ernst. We don’t have an alternative or replacement for those pots, yet. You can order some from us though, as we have them in stock. Contact us via email or through the contact form we have on our site: http://www.synthrotek.com/contact-info/

    Unfortunately, I can’t find the schematic for this. Is there a reason?

  9. Steve Harmon says:

    Hi Gabor, we don’t have this particular schematic available to the public.

    I orderd the wring flippin pots, have 500k alpha instead on B, will that be a major problem ?

    The only thing its going to change is how ‘quickly’ it reacts to you turning it. it will change slower at first, then real quick at the end, turning left to right.
