tube types?

[thevic24]

iam thinking of going out and getting a new set of tubes for my amp to see how diffrent tubes sound.

the amp has 2 12ax7's and 4 el84's. can i use any type of 12ax7 and el84 tubes in the amp? i guess what iam asking is are the types all the same?

60-35 is a date code (35th week of 1960). The type number is something
like 5Y3GT, 5U4G, etc.

A tube produced in 1960 should be of the highest quality, just like me!

yes it is a 5u4g, its a nos tube and was the most expencive part of the whole thing.

with the el84 tubes, can i change places(between the ruby and apmerex el84) with them or should they be left to the spots the are in?

i do want to get a "better" set of tubes. any suggestions, on which brand may work the best in this amp?


thanks.

a friend has some tubes(new)laying around that he says he dosnt need.
( he has a marshell head for his gutiar)

of thoes, the only ones that are the same as mine are some new in the box 12ax7's. the name on the box is groove tubes but the printing on the tubes say sovtek 12ax7wc.

its funny, the box says "...the american tube company since 1979" but the tubes are russian.

any how, are these good pre amp tubes for hifi use?
