I tell you, I really don't know how I've made it this long without one. I'd like to build a tube-type unit but it needs to have two antennae and be capable of all the expression and tones- and I need to be able to build it without having to solve a lot of mysteries. Seriously, at this stage in my life I'll build a Paia kit before I take on a project where nobody can actually tell me where to get the transformers
Hopefully, somebody has actually built one and will share their knowledge.
Maybe there's an uncompleted project for sale or for swap. (Think about it- Will you really ever finish it? 
I hope someone cand give me a little info. but seriously try your video store or Amazon- or Netflix if you're on it- and see this film
If it doesn't touch your heart then Buddy, you need to send in a Missing Organ Report. What happened to this man, though only touched upon in the film, shouldn't happen to the worst person in the World. There is a profoundly moving interview during his time in the Soviet Union where he is afraid to give almost any direct answer. Later it tells of the aftermath of a previous interview. Everyone should at least see this particular sequence at least five times to gain some small understanding and abhorrence of totalitarian regimes. Great interviews with Bob Moog and performances by Clara Rockmore that'll make you weep.
