"Great early analogue monosynth, serial number 0723, actually called the OB-1A. This version has livery like the OB-X, and it's reasonable to assume that internally it is very much like an OB-X voice with much more individual control. It is in very good working order, with the keyboard re-bushed in the last few weeks. Cosmetically it has some minor paint scrapes - hence our calling it 7/10 cosmetically. An experienced restorer could probably spend a couple of hours and get it back to near-mint. This synth has one mod, quite neatly done on the sloping panel behind the keyboard: a switch to send pitchbend to the CV out, with a corresponding amount knob. Switchable voltage, currently set to 240V with a UK plug. It has the Tauntek CPU mod. Packing 15GBP."

You can find another demo of one previously posted here.

"The cabinet is real wood with beautiful wood veneer. It's a simple compact unit that sounds great. It has an output and a footswitch jack at the rear. The front has two gorgeous aluminum ringed knobs to control volume and tempo and ten choices of rhythms to choose from. I really like Rock 2 but they are all pretty good. You can push down more than one at a time and really lose your damn mind. I cleaned the pots and switches and hit the wood with some lemon oil. It is ready to rock!

The YouTube video is old and of one I sold a few years ago. The video is terrible but gives you an idea of the sounds."

Buchla/Tiptop 292T RoHS | Buchla 200 series | Episode 13


video upload by Cinematic Laboratory

"This week, the 292t quad lo-pass gate finally arrived at the EU and the UK, but without the toxic vactrol components. As you may know, vactrols require the use of cadmium, which is mildly radio active and it should not end up in the environment. The 292t RoHS can safely be disposed when it turns out it ain't no Buchla anymore.

In this video I'll do a quick test using both versions but as always, TipTop Audio did a truly amazing job. It still has the magic of the original 292c, but it's a bit quicker because there's no vactrol memory effect. The bad news is that you can't strike it with a short blip, ping or trigger. The good news is that it sounds as tight as a doornail and when you use envelopes, you will not get the feeling it's not a 292.

Still, it's impossble they will respond in the exact same way. Even the original vactrol 292 would expose tiny differences from unit to unit, where the RoHS version will be consistent. I am a huge fan of LPG's and I always assumed you can't have a decent LPG without vactrols. The excellent Natural Gate from Rabid Elephant already proved me wrong a long time ago, and the 292t RoHS confirms it. There's no need to get yourself an 'original' 292t with an illegal import. The EU/UK version is fine!"
