Hi guys,
nice to see that the discussion is again flamed up.
My circuit with that Jfet cascode had, so far as I can remind, absolute no DC offset. I was running it without any capacitors in the signal way. I can agree Cheff, the sound was pretty well fast with deep bass. In the pas time I was on weight up what better, Aleph P or this. The time should show us. My project is on ice, but Ill continue as soon as my horns are build.

Good luck!
Adam

Those are particularly nice horns. I take it those are FE166 ES?

Default My completed schematic

1.Balanced source. (convert from Function Generator)
2.Balanced input module without de/increse gain.
3.Se input module with 10k potentiometre

Many guys mail me about my posted @ solidstate, Yes it's same schematic.

I have some problem with simulation when I use ZVN/P 3310 instead IRF610/9610 it's has more DC out on (drain+drain) output (0.5-1V) or I'll change source resistor from 1k to 221 ?

Help me please,I used 10.48mA each IRF610/9610.....too much ?

Thanks
analog guy

Just a few pics of the prototyped beast :

The "whole" setup, quickly breadboaded, wires everywhere, and absolutely no noise

Is there any way to not-use K389-J109, replacing with other "easy to get" transistors, without sacrificing the performance?

Haven't tried, so can't tell about better or worse performance. And you'd better match the fets.
