The most common rectifier used in higher powered amps which use a rectifier such as Fender 40 watt amps and Vox AC-30 amps.

Common to higher powered tube amps, like the later Fender Super Reverb amps and the Vox AC30 (or Matchless copies). It is the higher powered tube type rectifier in our marketplace. May be used to replace a 5U4 or 5Y3 and will give a faster more dynamic tonal result

This tube is based upon a tube which is considered something of an icon to EL34 users in both the audio world and guitar amp world. There were a number of variants of the original tube and GT chose the classic XF2 dual getter version to reproduce. The original was a classic and this tube is on it`s way to developing it`s own great track record just as the GT-6L6GE, E34LS, and KT88SV proprietary tubes. This tube is now available in matched quads and duets.

New European version with even more response, higher power and warmer tone.

Most common low power pentone, popularized in early Vox AC30 amps. Rediscovered by Matchless amps and now currently used by nearly every tube amp company. Quick, soft overdrive distortion, great for recording but usually too low volume for live gigs.

A faithful reproduction of the original General Electric "clear top" tube made on the original GE machines and with many original materials.

GT reissue which have a majority of USA components made on the original General Electric machines, the original tools, dies, materials and processing formulas as acquired from the liquidation for the last American tube factory in Owensboro Kentucky. Stunning clarity, and tone that is reminiscent of Carl Perkins through Jimi Hendrix... both of which mostly recorded through Fender amps in a period when they only use this tube. The most expensive (because of the the high US content)

Russian made, same as the 5881 you are using now, but when these are matched in our system they are improved. These are a very sturdy and reliable tube.

Perhaps the most reliable of the currently made types, with slightly less power and a more aggressive edge when pushed into distortion.

These are the tubes that are used by Fender in amps that use 6L6 tubes and are amps that DO NOT come from their custom shop. These are used in the Hot Rod series, Blues DeVille series, Pro Tube series, BF reissue series.

Groove Tubes E34LS matched power tubes quartet (4 valves). High power EL34 - round, dynamic tone, very durable.
