Blue glass envelope. The JJ Electronic E34L adds more power to a standard EL34 due to its higher grid voltage rating. This increase gives the tube more headroom and a tighter response on the low end. The wide frequency response of this tube offers excellent harmonics that work in a variety of genres ranging from the cleanest cleans to rich and aggressive breakup.

Superior "Black base" high-voltage power pentode. Most common power pentode found in British amplifiers such as Marshall, Hiwatt, Laney, and Sound City. The EL34EH defines the classic British rock sound of the 1960s and 1970s. Perfect EL34 for vintage equipment and for improved performance of modern amps. Extremely musical and predictable, with a sound that is rich, smooth, and detailed without being edgy.

Genalex Gold Lion KT77 beam-power tetrode tube. Made in Russia. A beam tetrode with an absolute maximum anode dissipation rating of 32 watts. The KT77 is designed for use in the output stage of an af amplifier. Two valves in Class AB1 give a continuous output of over 70 W.

Another classic from JJ. This tube features a rugged construction leading to an incredibly reliable EL34 with astonishing tone. Overall the sound is nicely balanced with tight lows, a rich and dynamic mid range and clear highs. The JJ EL34 is a great replacement for guitar amplifiers and stereo amps as well.

The wide frequency response of this tube offers excellent harmonics that work in a variety of genres ranging from the cleanest cleans to rich and aggressive breakup.

A true to form reproduction of a classic tube that will work in most EL34 amps. The 6CA7 is often considered the American cousin to the British EL34. Sonically, this tube is closer to a 6L6 than an EL34 but without the sometimes harsh high end of the 6L6.

A reproduction of the original tubes that captures the sound that made the KT77 famous. In their typical fashion, JJ has built this tube in a solid construction that is robust and highly reliable. This tube has more headroom than a typical EL34. This is an excellent tube for adding more power to the sound of an EL34 amp.

A different construction of the classic EL34 tube that offers a different tonal palette than the original. This tube has a more compact plate structure than standard EL34’s. The JJ EL34 II has an increased low to low-mid end with plenty of headroom to spare. The JJ EL34 II is stronger than the original but not harsh sounding in any way.

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.
