Lars: Good idea but you´re not the first one to think about using an Aleph-type CCS in an SE OTL amp, I wrote something about that on this forum at least two years ago. Never got any replies though...

The whole thing would be sort of a White follower.

Must have missed that, I´ve been busy lately and haven´t followed this thread as closely as I should.

Fuling,
Anyway, did you ever try it? Maybe we should give it a try? I have a ICA-plasticbag with at least 50pcs 6080s somewhere in my warehouse.

Gain is -7dB with 16ohm and -10dB with 8ohm so the driver must have good voltageswing capability.

Do you feel the design I originally posted has good driver voltage swing as is? I have already boarded up the amp I posted just need to do some tweaks and I will try the CCS and report back over weekend

Lars: No, I never tested any kind of CCS load. I remember being concerned about the startup process but I don´t remember exactly why

It wont work, in theory anyway! Not enough swing. Will come back with an adjustment if your circuit.

I was wrong! It will work, but the sensitivity is very high at 100mV rms. But keep it that way, you might want to add a tad of NFB to it later.

NFB would be good anyway to reduce the output impedance etc.
