This is a clone of the Buchla 258 oscillator. Despite what some people might tell you, it is totally true to the original in sound and response. I made all the electronics fit between the panel controls on a single PCB, as opposed to wiring to it like the original. I replaced the obsolete heated transistor pair with a modern matched pair and a tempco. The CV inputs respond exactly the same as a 258c. This one has the CV input fine tune control on the left, but I will be doing them with a grey banana jack in place of that. It will be trimmed to 1.2v/octave, but the other CV inputs are unaltered. Now I just have to build the rest of these....

Campari sold separately.
Are these for sale?
Mark - your work is absolutely fantastic!
Are those mini-dials the 9mm alpha types? I've just started using those and found the unpainted direction indicator really annoying. I found, though, that you can use a little bit of wire, dip it in some enamel paint, drip that into the notch and then quickly use you finger to wipe off the excess -- seems to work a treat.
Woof!
are these only available for sale for a limited time, or will there be a few runs? cheers
Everything I build is custom work, built to order. Not really in "runs."
I've looked at some demo of this unit and am really interested. have you got a link for prices and how long it would take?
Amazing work Mark!
Would it still be possible to order one?
email me.
