Eli, I don't want to hijack this thread, but I notice in the 12AQ5 schematic that you're using a CCS at the splitter cathodes. Along those lines, have you considered also using something more "predictable" to bias the outputs? Not a CCS, but maybe an IC voltage source like the "enhanced bias" technique that's been discussed here previously? You know, the more ways I find to test push pull output stages that use the standard cathode bias technique, the less I like it. I think there might be significant advantages in most PP amps to nailing this down.
