The former are still in my system, now driven again by the FirstWatt J2s*. I've started to simplify my audio/video system, and that means, initially, reducing the number of vacuumtubes in it. The J2s have only about 40 hours on them, but they're sounding better all the time. I've improved some parts in them...

* Another of Nelson Pass's low-volume interesting-circuit-and-parts exersizes, this one using all J-FETs. Rated at 25WPC into 8 or 4, mine have their channels paralleled for 25 into 8 or 50 into 4, per chassis.
