T-KT120-TUNG Vacuum Tube - KT120, Tung-Sol Reissue
Tung Sol KT120 power pentode tube. Made in Russia. In September of 1950 Tung-Sol introduced the 5881, an uprated and industrial version of the 6L6GA with a 23.5 watt plate dissipation, opening the doors to the hi-fi movement of the 1950s. This rugged tube also found a home in the '59 Fender Bassman and servo amplifiers used in B-52 bombers. In 1955 Tung-Sol raised the bar of high fidelity with the introduction of the 35 watt 6550, which could deliver 100 watts with a pair in push-pull configuration. This tube was used in the Dynaco Mark III and Sunn amplifers.

T-EL34M-MP-GT Vacuum Tube - EL34, Groove Tubes, Matched Pair
Package of 2
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.
