EL34 types

[adalin]

HI

I was shopping for some new sparepart tubes for my amp and found out that there is some different tubes out there.

I have not cared about this before but now I started to think about it.

There is the usual EL34 and then there is EL34G, EL34WXT, EL34EH ect

What is the difference between these tubes and other letter variations?

What I have heard is that the G stands for graphite.

Does this mean that the EL34G has graphite plates?


And does they have different performance like the 6L6 types?

Hi,

EL34G, the G suffix normally stands for GLASS as opposed to METAL.
To the best of my knowledge no EL34M (metal version) ever existed so I suppose you can just as well ignore it.

The USSR (probably Reklector) EL34WXT should be a ruggedized EL34 with extended life (aka long life version) similar to the NOS E34L professional standard.

EL34EH, the EH is just a vendor's suffix and stands for Electro Harmonix.
EH sometimes has some types especially made for them according to a NOS manufacturers' specs.

And does they have different performance like the 6L6 types?

Most I know of have all very similar electrical specs but there probably is an audible difference between various types.
This is kind of sound tuning is always popular among guitar players.
