Group,
I played around with my TT EZ-build and replaced the final with a 2n2222a in a T0-18 case with a heat sink. I think I had the original transistor in wrong so got a much smaller output. (conjecture). because the printed circuit board had the round symbol and the flat side should be facing toward the Base. The socket I put on the board covered most of the writing so I just assumed the flat side orientation would be the same as the other drawings for the non-round transistors. Lesson learned.
When dialed up it showed .74w into a 50 ohm dummy.
? ?Enjoy,
