Vacuum Tube - EL34, Groove Tubes, Matched Pair

Package of 2
Sold as a package of 2
In Stock

Octal power tube (Max Plate Watts = 25W) The GT EL34 is based on the original Mullard® EL34 of the '60s - the stock tube in all early Marshall® and Hiwatt® amps. Mullard produced it for about 15 years, and this is a faithful reproduction of the classic XF2 dual-getter version. It has a big, fat and well-defined tone and really “wakes up" reissue amps to perform like the originals. As close as you can get to vintage Marshall® power tube heaven.

This is the way we get the tubes from Groove Tube. If you want a quad you can order two pairs and we will try to match up two pairs depending on our current availability.

If the tubes you are replacing are El34's you should be fine. The El34 has an 8 pin pinout.

You will need to take your amp to a tech in order to swap from 6550 to EL34's. The amp will need a rebias and some resistors will need to be changed. We are not techs and can not advise you on how to do this procedure.

These Groove tubes are made in China. They are based on Mullard's and not necessarily a exact reproduction. We do sell reissue Mullard's that are exact modern reproductions. You can find them by searching for T-EL34-MUL. JJ's are a brand of tubes made in Slovak Republic. We recommend that you give us a call at 480-296-0890 to determine the right tube for your application.

Yes, towards the end of the online checkout process you will find a notes section. In that section state your required rating and we will match it with our current inventory.

The T-EL34-MUL are reissues of Mullard El34's. These Groove Tubes are based on the original Mullards and are not necessarily a reissue.

I purchased these for my brothers JCM800. He was floored as to how much louder his amp now sounds... He was very happy (once the walls stopped vibrating). Thank you.
