Didn't someone (maybe Tim de Paravicini) do this with 12AX7s?

The single-ended version typically requires four times as
many devices for the same performance - 2 X in parallel and
then balanced.

It's actually more economical to go complementary when you
consider your time and the costs of the extra transistors,
resistors, and pc boards.

Oh, and it will not be an F4.

Variac and Elena and Jill and I all went to see Thievery Corporation at the Warfield a couple years back.

The performances were awesome but the sound system sucked.

The kilofet; a new unit of excellence?

Very interesting! I look forward to following the progress on this.

Jeez - how many 2sk170s do you need to come up with a matched millennia?
