Getting the best from PM Guitar Tubes

PM Sets are perfectly matched – the tubes you re replacing probably weren t when originally fitted, so the BIAS on your amp will have been adjusted to a different value for each tube to ensure even performance If the amp is self-biasing or user adjustable, no problem! If a fixed bias type it will need to be setup by an engineer, a simple job (for him!) Check your amp s handbook before replacing Incorrectly biased amps reduce tube life and performance, invalidate our guarantee and worst of all sound bad!

Did you know???
That the 12AU7 ECC82 are the same thing! One is a British code one is an American code, but the valve itself is identical!
