Jeff, I thought the JJ 40 was a 300B with a 2.5V filament.
I agree about the 2.5k primary impedance. I think the Magnequest DS025 is an astonishingly good output transformer at a very reasonable price. I have op transformers from several of the other premium winders and I just can't quit listening to the DS-025s!
