I built this one a couple years ago, just never got around to posting its mugshots. This is the topside / frontal view.

Stereo, approximately 2 Watts per channel, using 13EM7s, which were originally intended for use as the vertical deflection oscillator and amplifier in TV sets. This is all crammed into and onto a 10 X 6 X 2 inch steel chassis, it was kinda like trying to pack 10 pounds of "fertilizer" into a five pound bag... Good results using inexpensive parts, that's the name of the game.

This is essentially a half-sized and simplified version of [id=249740385; another amplifier] which I built previously.
