Input is 12AU7. The output tubes are JJ EL509S.
I just made the "lite" version, with four output tubes per channel. I wanted to fit the whole stereo amp onto one chassis, rather than two monoblocks each with a separate power supply chassis as in Alan Kimmel's original article. It is a bit of a squeeze, and there's an outboard fan at the back, and the heater toroidal transformer too, like a spare tyre on an SUV.
