A good 300B tube is expensive and hard to find..let alone the amp. One of the few considered king of the valves to audiophiles, especially to oldies. Perhaps, one of the best in the world as S.E.P.P. amplification tube when match with "loud speakers". Interesting indeed that is used in pre-amp as voltage amp instead of current. Very rare and wonder how good it works. Nice for HK 土炮 . |
