Electro-Harmonix 6550EH - $79.95  pair/duet
Great tube for Ampeg SVT's and SUNN amps! The 6550EH offers excellent linearity, power handling capacity and heat dissipation. Four-pillar construction and mica spacers help maintain a rugged mechanical reliability. Offers classic tones at high volumes/levels. The 6550EH is a great modern production tube for any amp using 6550 or KT88. Special order.

Electro-Harmonix 6CA7EH - $44.95  pair/duet
Designed after the Philips/Sylvania 6CA7 tube that EVH used back in the day. Great in the bottom end, punchy in the mids and smooth/open on the top end.

Electro-Harmonix EL34EH - $36.95  pair/duet
Smooth, rich, lean in the lower mids and very musical. Great for older EL34 amps, older Marshalls and high gain amps. According to the technical journal, Vacuum Tube Valley, the "...new EL34-EH tube comes very close to the sonics of a Mullard EL34..." They go on to say, "The Electro-Harmonix tube is balanced throughout the entire music spectrum. Bass goes deep and is tight, mids are sweet and well defined and highs are detailed and extended." Special Order.

Electro-Harmonix EL84EH - $26.95  pair/duet
Great in Vox AC30's and other EL84 based amps. Electro Harmonix faithfully recreates the classic Mullard design. Tri-lam plate material and selected screen wire increase thermal dissipation. The EL84-EH tube is a remarkable reproduction of a vintage tube that is capable of maintaining its sweet and musical tone under any voltage conditions. They do tend to pull more current. Special Order.

Electro-Harmonix KT88EH - $68.95  pair/duet
An improved version! The new KT88EH tube is here. In this KT88 tube, a new geometry is utilized to reduce odd order harmonics for a sweet top end while the peak power is extended to improve low frequency response.

Tung Sol 6V6GT - $39.95  pair/duet
Smooth and creamy! For vintage 6V6 tones this tube is hard to beat.

A must for blues players! Special Order.

Tung Sol EL34B - $54.95  pair/duet
Not your typical EL34 as it blends together characteristics of an EL34 and a 6L6.
