I'm building a Fender champ style amp. Using a 6l6 instead of 6v6. The problem is the power I'm getting out. About .5 watts. I've checked the voltages on the 6l6 its 360v on the plate 345v on g2 the tube is drawing current around 50ma everything seems normal but no power or very litle I even tried a diferent OT same thing. I'm sure the problem is simple but i dont know were else to look. This is not my first champ build my other one puts out over 5w. I need some help please!
Thanx
Mario.

Schematic? Scope? Wrong NFB resistor?
What is the cathode voltage and resistor on the 6L6? What is the p-p voltage on the grid of the 6L6 before clipping/clamping is observed?

Perhaps one of the earlier stages is goofy,and isn't sending enough signal to the grid of the 6L6? Just a random thought.
