Published
In this video I go over the most frequently asked questions and do some modifications to the circuit and tell you why.

This amp produces around 1.5 - 2 watts of sonic goodness! (I was blown away!)
These TV tubes have a wide range 25Hz - 21,000Hz (dependant on the OT used)
Deep bass, crisp/bright highs and a wide sound stage.

Specs:
Two 6DN7 vacuum tubes (1 per channel)
Two 5k Primary - 8ohm output transformer (i.e. Hammond 125BSE)
One 275-0-275 ~80ma power transformer (i.e. Hammond 270CX, 270DV, 271X)
