Changement de tubes

[TBM]

Réponse concernant les mesures :

We use a Maximatcher pre amp tester for the small tubes and a Maximatcher tester for the power tubes, but neither one gives us the option of selecting the specifications for testing each tube. Those are built into the tester's software and are set automatically when you set which tube you are testing.

These two tube testers are considered to be the best ones for matching tubes and we have found that over the years they do an excellent job of measuring tubes and allowing us to offer nicely matched pairs.

All this should not matter with you monoblocs as they are self biasing and the tubes do not need to be matched. Just adjust the bias for one of the tubes and the amp automatically adjusts the other five tubes.

*pour cette dernière partie, j’ai du redire que j’ai besoin de 2 matched pairs de 6550 , c’est bien ça, non?
