THERE ARE NUMBERS ON MY TUBES

[bmast160]

i bought two sets of JJ EL84's and each quartet has numbers written on the box...32.3 8500, 32.8 8300, 32.7 8300, 32.6 8280 the other set has 33 8300, 33 8300, 33.1 8060, 33.8 8430...this doesnt refer to any matching of tubes right? probably just for the store?

i ordered one quartet for a vox ac30cc2 and one quartet for a cratev3112 does it matter which quartet i put in which amp...and does it matter which order i put the tubes in in each the four sockets???

The large number is GM, the other is the current draw. They did this so they could grab matching numbers and make matched sets out of them. No, it doesn't matter which one goes in first, just put them in. Both sets are very close together, you could mix them and you wouldn't have any problems.

 

 

not that i really need to know but whats gm?

thanks for your help!

BTW, the current and GM aren't constant in a tube, they will vary depending on the operating parameters. Different tube vendors may have different test fixtures so the numbers from one vendor won't necessarily correlate to the numbers from another vendor and certainly don't indicate what the bias will be when installed in your amp. They only indicate matching when compared with values measured on the same test fixture.
