Alexei Semin assembled the Circlotron according to the circuit with an interstage transformer.

I’ve ordered two big cases from Gianluca over on the Pass forum and I’m seriously thinking of building this circlotron with these as output devices: https://www.mouser.ch/ProductDetail...cjbzSfp1HmcdgVquUvSSfNXmeAUj/AkiBiQjZpDl1Sw==
Hope I won’t change my mind in the next month

I have already these in my possession so i will also build with these, but I would try the 65K3S
I ran an circuit on 2SK2145. At the exit I put IRF4905 ( P-channel), which I found in my nightstand.
Square wave - 60 kHz. Output stage current - 180 mA.

When the amplifier is turned on, the current starts to decrease slightly and stops after J174 warms up. This is due to the drift of the J174.
After that, the current is stable on massive radiators.

Thank you both 🙂
I try to simulate the protection under ltspice to compare with what I already have, but I cannot find a PC813, PC814 or TLP620, by the way Mouser does not have one too, you have other references?
