With over 25 years of experience in development and manufacturing of electron tubes, our staff is ready to meet the demands of today`s HI-FI and music instruments markets.

JJ Testing
Every tube is electrically tested for parameters such as isolation characteristics, the electrode's current levels covering the entire operating curve, the condition of the vacuum, cathode emission capability, filament voltage and current levels. A microphonic test is performed on every tube. All tubes are then further burned-in for a period of 24 hours at the nominal specified operating voltage and current levels. Every month, a random sample is taken from the production to perform a life test of 5 000 hours at nominal operating conditions or 1000 hours at maximum specified levels.

Recensione

Puntuale arriva il prezioso pacco.come suoneranno queste jjel84? Andranno in sostituzione delle sovtek buone valvole.lla differenza dopo un riscaldamento durato 2 ore e la dinamica superiore a qualsiasi potenza e frequenza medi e alti ottimi bassi presenti ma mai invadenti ottimi .ora e pur vero che le valvole influiscono in minima parte al suono quello che conta e il circuito dove operano pero queste jj anno una altra marcia e vincono su sovtek 6/0.la qualita che ho ricevuto soffre un po microfonicita ma il90% delle valvole e cosi anche le sovtek e pure peggio.mettero se funzionano degli anelli smorzanti.grazie a playstereo per la collaborazione.
