I have about 3-40 tubes 6AN5WA.Can I use them in OTL tube amp?
I use in SE Amp, Sound very goods but low watts.

You'd need a bunch of them, as the Pd= 4.0W is quite low. They might work if you trioded them, but the usual suspects for a VT OTL would be something like the 6AS7. The problem with paralleling is that some folks out there think they sound "off", whereas others don't seem to notice.

You could do a Circlotron design with 20 6AN7s per phase. Atmasphere has some of their bigger amps paralleling that many 6AS7 sections. Just be sure to include some sort of DC offset detect/correct circuit so you don't poof a speek.
