The problem with a 300b is that it's a low gain tube. Hence people resort to using IDHT drivers, so you lose the all-DHT sound. Personally I'm not willing to use IDHTs - for me they subtly veil the sound and lack that DHT see-through transparency.So my solution would be to use an output tube with at least a gain of 8 or 10. With a 4P1L driver this gives you a 2-stage amp that works with speakers of moderate sensitivity. Not necessarily horns - full-range units like Alpairs or Fostex or Lowther work okay.
Output stage doesn't have to be 4P1L - could be another higher gain tube like PX25, 813, 211, 801.
