I hope the new 2A3-40 can get enough power from a PP amplifier to alleviate foregoing the search for another output tube for more power.

The amplifier that Douglas was working on might be a good PP design for a set of these tubes.

Possibly the 300B SET circuit that you are perfecting could be a good candidate for utilizing the 2A3-40 if so desired?

How much power do you feel is obtainable from these new JJ 2A3-40's?

I did see the KT-77, it looks good to me. I have been trying to talk a freind of mine into trying a set in his Eastern Electric M520.
But, he is set on trying the Mullard clone EL34 from Russia first.

Let us know about these JJ 2A3 tubes if you get the chance to try any? They look like a possible high quality alternative to the Full Music 2A3's. They are priced about the same.
