Taking a second look, I may not need the single row PS caps, as it really doesn't save all that much space. But since Iv'e put some time in it, does this look proper?

My apologies, all this probably should be over on the PS thread.

If you want one pair of R100 per channel, that sounds like a perfect job for the F6. It was designed for exactily that.

And, it uses the R100 to best effect, not being a follower, you hear the intrinsic awesomeness of the power Jfet.

Thanks. Sometimes it's easy to see what we want to see without a proofreader.

The PS design for the BA-3 project was changed to what 6L6 posted. If interested, the fabrication process can be seen HERE

Exactly, satisfies the urge to craft something unique even when not completely necessary.

For those interested in Keratherm I have just used it to mount mosfets onto the heatsinks. Came in sheet form, which was easy to cut with scissors and an old punch for putting holes in leather belts. Easier to work with when mounting the mosfets because no requirement for grease unlike the mica pieces I previously used. Can get Keratherm from Young Electrical Group here in the UK if anyone interested but mica is cheaper.

That's because it depends,

...on both PSU voltage and output devices.

If you look at the power output graphs on the various pages in the BA-3 article you can see where the distortion goes through the roof -- that point is the max power output: roughly 25WPC with 24V rails, and about 50WPC with 32V rails.

More output devices gets you more current, which will translate into more watts into lower impedance loads.
