JJ-Tesla 300B Selected Pair Tubes

These are a great alternative to the higher priced and hard-to-find 300B tubes. The JJ 300B do have excellent musical and construction qualities.

These JJ 300B, with ceramic base, are precision factory selected in pairs or quartets. Every single tube is tested on three parameters and it is included a complete test certificate. Six months warranty.


We now stock the new super-high quality JJ audio tubes. These tubes have consistently outperformed the competition in tone and sonic performance. Quality is the best we have seen from this factory.
