Alternatives for the 12BH7 Amplifier Valve

If you are buying the 12BH7 for a small practice amplifier like the Blackstar HT-5 amplifier to ensure you get the best performance it is recomended to buy the official electro-harmonix product or higher priced items that have gold pins. Current production of the 12BH7A from Electro-Harmonix is a direct replacement for any amplifiers with the 12BH7 and 12BH7A tubes. The JJ Electronic ECC99 is a compatible driver tube, it can be used as a substitute for 12BH7 in many cases, but please refer to amp manufacturer’s recommendation if you are not sure.

Is your Guitar Amplifier Struggling? Has the output sound begun to degrade and break up? Are you experiencing additional noise and distortion? If yes, then it is time to consider replacing some or all of the valves in your guitar amplifier. Guitar amplifier valves (or tubes as they are known in the USA) are robust and will work for many hours. Performance will be affected by mistreating them or allowing them to overheat. Generally the performance of vacuum tubes starts to degrades with the amount of time they are used and up to 1000 hours is typically the optimum life of a valve or tube.

If the performance of your amplifier is failing then it is likely that some or all of the valves need replacement. When replacing guitar amplifier valves it is best to use matched pairs as this will ensure the valves last as long as possible with the best sound quality. We have a full range of replacement guitar amplifier valves and matched sets available for the most popular amplifier types – see the links above.
