I just discovered this version of the original Miniwatt S1 SET amp on Amazon.
This is a true SET using four tubes ( 6J1 and 6P1 ) which differs from the three tube single ended APPJ N3 ( EL84 and 12AX7 ).
I've spent time with the more expensive N3 and while it sounded very good I always thought the S1 was better. Could be due to the diode mod that was popular when the MW first hit the market or the upgraded 6p1-ev Russians and WE 403B's.
At $169 shipped this is one hell of an amp deal. I think it would go toe to toe with a number of thousand dollar SET amps.
