An externally hosted image should be here but it was not working when we last tested it.
This is a Zenitron variation on Zen v.8.
No in or output caps. Just one big choke, 2 x 150 mH 0,6 ohms DCR.
Any feedback will be appreciated!
(I just need som Lovoltecs to build it.)

I saw that the power supplies had the wrong polarity.

Something like this.

I was very tired yesterday. I made some mistakes when drawing this amp. Im not used to drawing on my computer....
Input is at R6 and R7.
I would be very happy if I could get some feedback from all you out there.

I guess you are not the "Circlotron" member from some time ago. Forgive me for not looking up those threads. Those posts were full of ideas but I beleive most of them were for a voltage gain version, common source...
I've been working on a very similar thing, JFET/Cascoded in a Circlotron output. The output works very good in simulation. It's a simple "Zen-like" driver that I've had to experiment so much with. What do you plan on driving this circuit with???
I also wonder about the L's in the source??? But what about the .22ohms?? I beleive thay may be usefull as a source R but they are not in exactly that configuration??? They should be in place of the L's???

The" Ls" are a bifilare winded 2 X 150 mH choke, It fuction is to shield the signal from the drain to feed back around the circuit and make a voltage follower output from this circuit.
This circuit has voltagegain. The 0,22 Ohms resistors are just some local source-feedback to make the circuit stable and nice. They are probably not needed.
There is more info about this circuit in some of my own threads about the Zenitron.
