JT,
TJ also makes PX25/5V (5 Volt version)tubes that can replace 300B's. The look is awesome but I have yet to try them. The tubes that I'm listening to right now are Sovtek 5AR4 x 1, Sylvania 6f6g x 2, EH6SN7 x 2 and TJ PX4 x 2. If I would like to pamper myself, I would plug in my collection of NU350B's, Mullard GZ34's and CV1988's. YMMV.
