Why 300Bs?


I often see these tubes mentioned with a great deal of reverence, but have never heard an amp that uses them. What is it about this tube in particular that commands such admiration (and premium price) over other tube types? How is its high frequency extension? Why so big for such low power output?

Simplicity, purity, linear, euphonic and most importantly: class-A operation. Depends on how much power you need, it is probably the same reason why folks go after other SET output tube amps like KT88(in triode mode), 845, 211, px25, 2A3, and 45.
The cheaper version would be EL84 SET which also sound quite good too. In most cases, the bigger the tube the more power and more stability you get.
You need to get out more often to hear one. Start with the famous Jadis 300B amps then listen to these Chinese clones. In my opinion, you'll notice that all 300B amps are not create equal.
