At last a Front Panel...

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!

On the Board!

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...

CRO says No...

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...

VCO to the max...

Here are 6 VCO's waiting for temco's, final tuning & a front panel... There are two from Mr Henry, a MFOS, a Yusynth, a CGS and a Buchla clone.

All Lined Up...

We really need to do something about those front Panels!

Polivoks Filter

This is my rather crusty layout of the Polyvoks Filter... Guess who got the press'n'peel back to front?

OC71 & LM394

Well the OC71 is at least 40 years old (I remember my parents buying the Radio that I pulled it out of) and the LM394 is from week 42 of 1988...
