that way I'll have enclosures too deep ........

so - I decided to Sonido-fy recently traded EV12TRXB , which are 12" coax spks (Sonido-fy means - take them for recone to Varga ) and make proper tall MLTL for them , which hopefully doesn't need much deepness ........

so - I just passed Sonido 8" to proper place and I'll be using 12" EV-Sonido coax


speaking of that ..... why you're using Fostex , instead of Sonido - which is local to you ..... ?

I don't know. Is there some particular reason you prefer a
circlotron?

The possibility of having the simplest circlotron which doesn't self-destruct

The whole joy of DIY is making jokes, assumptions having fun. Now we wonder what's Papa's next secret device, or how does it work. Sometimes we guess right, sometimes we miss, but it's fun. It would be just plain boring if Papa would simply put the finished schematics out there; he wants to see us use some grey cells, and not just copy/paste.

Seems to me to be a logical step to fold half of an F5 into a circlotron and replace the output fets with Jfets.

Simple, minimul, Zen-Like, even if it's only a follower! The prototype I built drifted around to much? I suppose the real trick is to find gain devices with 0 temperature coefficient, that can operate at a convenient Iq, and having semetrical curves while swinging + and - current.
