The Blackstar Series One 104 EL34 amplifier uses 4 x ECC83 (also called 12AX7), 1 x ECC82 (12AU7) and 4 x EL34 matched power valves/power tubes.
Over time these valves slowly lose both their tone and their power. So a brand new set of valves will get your amp sounding like new again. We always recommend JJ valves for this amplifier. This is because they guarantee you get awesome tone and long life – and they don’t cost a fortune. Remember, JJ is one of only five valve manufacturers in the world.
So don’t pay higher prices for valves from the same factory that have simply been rebranded.
So restore the tone, the power and the sparkle to your guitar amplifier. Treat yourself to a brand new set of valves today.

About the Blackstar Series 1 104EL34 amp:
Four EL34 power valves form the backbone of this 100W high gain power house and provide unbelievable dynamics and head-room. The DPR control allows the power to be reduced down to 10W. So this means you can get beautiful power amp distortion at a much lower volume level.
Setting new standards in tonal flexibility, the deceptively simple preamp section has four world-beating channels (6 modes). In addition, these are further augmented by dual ISF controls.
