    I say PFB should jump all over them.
    Good music, a good source, and good power can make SDA's sing. Tubes make them dance.

    Is a 300A an equivalent to a 300B?

    from what I understand yes just a little different base

    The Western Electric 300B resulted from a slight modification to the Western Electric 300A vacuum tube that was introduced in 1935, which was used in the previous models of Western Electric audio amplifiers like the 92A. The photo below shows a typical commercial installation of audio amplifiers for the time period. Note the pullout turntable in the rack above the 92A amplifiers.

    300B

    Single-ended-triode vacuum tubes & amplifiers like the Western Electric 300B & 91A started fading from the scene when the higher power Williamson push-pull circuit utilizing negative feedback, and more powerful vacuum tubes like KT66, appeared in 1947. By the middle of the 1970s the world had almost completely forgotten about the Western Electric 300B & 91A. The single-ended-triode fires had burned down to a faint glow and were ready to pass into a state of extinction, but then something wonderful happened: Japanese audiophiles rediscovered 300B directly-heated single-ended-triode vacuum tubes in the late 1970s and resurrected the 300B SET amplifier.

    Japanese audiophiles noticed how good the 300B SET amplifiers were both musically and sonically, and they started quietly buying up vintage American vacuum tubes like the Western Electric 300B, vintage American tube amps like the Western Electric 91A, and vintage speakers that were designed to be used with low powered vacuum tube amplifiers (like the Tannoy series of Dual Concentric™ speakers and enclosures, and the Altec Voice of the Theatre loudspeakers (Altec was a spin off company of Western Electric incidentally)).
