"Living VCOs" PCB in 2009 ?
2008-12-07 by JH.
Hi, I got several requests for a VCO like I have in my JH-5, something that doesn't have the focus on precision but on character, with "linear detuning", and some of that early Moog and EMS character (without being a clone): http://jhaible.heim.at/jh5/jh5.html The main reason why I hesitated so long was as simple as it was embarrassing: I couln't find my design documents - I must have lost them in moving houses some years ago. The prospect was that'd I'd have to reverse-engineer my own prototype if I wanted to offer a PCB for this ... But some days ago, I found my PSpice simulation files, which show the main parts of the VCO and VCO driver circuits in a form that must be very close to what I've actually built in the JH-5. So, suddenly the possibility is there ... JH.
