Products > Full Revalve Kits > Blackstar HT Stage Series

These full revalve kits use specially chosen valves to help you attain the sound that you are looking for from your amplifier. The valves have been specially chosen for their sound characteristic. They are specially position matched as to their function in your amplifier. They are selected for gain, triode balance, low noise and microphonics. These kits are backed by over 25 years of experience in selecting pre amp valves for professional musicians who trust their sound to Watford valves.

Blackstar HT Stage Series uses the classic British sounding valve, The mighty EL34. These amps have the tonal character of the great British amps of yesteryear. We have chosen the best of the EL34 to enable you to get the best out of these amplifiers.
