Electro Harmonix 6CA7


Product Description

Electro-Harmonix 6CA7 - This tube is very similar sonically to the Electro Harmonix EL34, but in a shorter fat bottle design, so we call it a 6CA7. Some folks might find the larger bottle more aesthetically pleasing, or if the tubes are in a tight area the shorter bottle may be more appropriate.

A little more energy than the SED Winged C, so if you need a little more clarity and "pop" on top end, this may be the ticket. They're dependable too, especially after our Tubezilla screening.

Pricing above includes matching in any quantity you need at no extra charge.

All power tubes are Platinum Screened & Tested to the highest standards, including a 72-hour burn in process, and testing at real-world voltages.

  1. Excellent EL34 tube for Hi FI systems

    Posted by Marcus N. on 12th Oct 2011

    A nearly dead-on copy of the Sylvania/Phillips version of the only truly American EL34, the big bottle 6CA7(no other EL34 variant of the golden era was ever made in the US!).Like the originals, these bias a little "hotter" than a regular EL34 tube and provide a very warm, powerful signal, with noticeably more volume at lower power levels.And yes they do look cool with a 6550-esque vibe.
