The Blackstar HT Studio 20 and Studio 20H (the head version) amplifier use 2 x ECC83 (also called 12AX7) preamp valves and 2 x EL34 matched power valves.
Over time your valves slowly lose both their tone and their power. Replace them on a regular basis to maintain the full tone of your amp. We always recommend JJ valves for Blackstar Studio 20 amplifier. This is because they guarantee awesome tone and power. They also give you long life – all at a very competitive price.
Remember, JJ is one of only five valve manufacturers in the world. So don’t pay more for all those over-priced rebranded versions of the exact same valve.
So bring back the power and sparkle to your guitar amplifier. Treat yourself, and your amp, to a brand new set of valves today.
