Ok! :)
It`s just so easy put together with few parts, that it would be fun to build!

Just thinking out loud here...:

I`m having 300VA trafo 2x15v sec. so can also get out 38v.
Find that the original 110v 300w bulb is 40ohm.
Article says 12v on Drain for Mosfet -> 28v over bulb? -> Bias 0,7A? (With 40v PSU)

Transforming into two 24v bulbs in series they will need to be about 72w each?

Am I on deep water or....? :)

Can I use the 300VA trafo or should I forget it all?
 
I am running an IRFP150 at 1,0 amp and 10 volts D-S, with only 1,0 ohm source degeneration, and it works just fine. I don´t get more then 1,7 watts from the amp, but with very efficient BIB loudspeakers it enough for me.

The amp sounds very clean and precise. I can´t hear any distortion or lack of definition.

regards,
Johannes

This is the amp as it is playing now. It is a rats-nest point to point build, to test a no (global) feedback as simple as possible Zen amp.

Johannes
