Ruby EL34BSTR
This new high gain EL34 from the Shuguang factory has dynamic tone, a thicker glass envelope and gold plated grid.
Ruby Winged "C" EL34
Same Winged "C" from St. Petersburg, just a different box. These tubes match well. We have specs that match up for Bogner Amps.
EH EL34
This is an extremely musical tube very highly detailed, rich and smooth very close sonically to the Mullards.
SED EL34
Formerly known as Svetlana, Made in St. Petersburg, Russia. This tube has a smooth midrange with a top end that shimmers with that familiar EL34 growl. There is a lot of extra hand work with this tube. The SED EL34 has a gold plated molybdenum alloy grid and carbon coated screen grid.
Svetlana EL34
Another tube close in sound to the Mullard, you have silky highs and musical rich midrange here. Distributed by New Sensor Corp.
JJ KT77
I finally got a chance to really listen to this new tube from JJ Electronics and really like it. For the most part these will bias up like the EL34/6CA7, but looks like around 10% of them have high enough natural current draw to replace a 6L6 or 6550(Check with your amp tech). Expect to hear crystal clear 3-D cleans, extended lows and highs, and very thick articulate breakup.
Mullard EL34
This is the xf4 Mullard reissue from new Sensor Corp. The overall tone has balanced mids and is very warm.
JJ E34L
In Stock. Same as the EL34, but with 20% more headroom than the EL34. Older stock, older style pins.
GT-E34-LS
Slovakian EL34, similar to JJ E34L but with heat sink wings and 30 watts plate dissipation.

Reproduction of a classic EL-34 XF2 Dual Getter tube. There were a number of variants of the original tube and GT chose the classic XF2 dual getter version to reproduce.
