Actually did this a week or so ago but I do now have a panel... This is for the Thomas Henry XR VCO. I need more of the Cliff sockets and the real potentiometers but we are getting there slowly!
Well the Tooob has made it onto the board... not a lot of success so far as the two diodes protecting the heaters seem to be too aggressive in their conduction levels so we are only driving about 0.7V in instead of 1.5V... looks like two in series coming up...
This was the output from the Buchla 258 VCO clone... the Triangle seemed very offset, as you can see from the photograph, but it did come good after the Q9 transistor was changed to a PN3638A, which I had lying around... Now trying to match the Sinewave modifying FET...
