That looks pretty cool, but its still running as a common drain amplifier, right? My tube preamp doesn't have enough gain to drive a MoFo to anything past about 1.5w . That's why I'm kinda trying to make a common source MoFo that has at least some voltage gain (and no feedback I suppose in this case).

Also, are you using microwave oven transformers for the chokes? How much inductance do they have?

You need a high swinging preamp capable of 40Vpp with low distortion. Look no further than Aksa Lender or Yarra/Melbourne.

AKSA's Lender Preamp with 40Vpp Ouput GB

The YARRA Preamplifier/HPA for Melbourne DB Group Buy

And Btw, the amp sounds fantastic with the 10F/RS225 FAST speakers (which I think you know how they sound).

But then why don't you just make the ABBB - a 52w SE Class A amp with hybrid Aleph active CCS? The ABBB is a complete package with state of the art PSU with active bridge/CRC/Cap Mx and SSR DC protection all built in. Just connect a 400w 32v trafo per channel and speakers.

The Alpha Big Boy with Buttah (ABBB) 52w Class A Amp GB

Ok, I finally got around to making a proper schematic of what I want to build. It's really just a combination of the De-Luxe De-Lite circuit with the L'Amp 193V power supply.

Click the image to open in full size.

I remember reading that inductor loaded amps are trickier to bias than those with an active or resistor load. Can anyone shed some light on this? Would it require a scope to measure the output and its distortion?

Might be a neat thing to build, make a couple monoblocks on some nice pieces of wood. I just want to make sure that the circuit isn't so bad that I can't fix it if it doesn't work. I do want to try something riskier than my ACA though
