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.

  • Tubes being sent in for warranty must have a return authorization number from Upscale Audio. This RA number must be written on the outside of the box. Please also include a note in the box that has your name and telephone number, and please explain the issues with the tube. If this information is missing it will delay the shipment of your replacement tube.
  • Vacuum tubes being sent to Upscale Audio for warranty replacement must be shipped in a box with appropriate packaging to keep them from being damaged. Vacuum tubes returned to Upscale Audio using inadequate packing will have a voided warranty and will be refused at the customer's expense.


Exceptions to our warranty policy are as follows:

  • Upscale Audio reserves the right to refuse warranty at our disgretion based on the equipment being re-tubed. You will be notified of any change prior to your order being processed.
  • Using a tube in an application in which it was not meant to be used. If your amp calls for a 6550, and you decide you want to plug in a 6V6GT, Upscale Audio is not liable if the tube fails, and will not honor any warranty in such a situation.

Upscale Audio is not liable for any damage or injury caused by the improper use of its tubes or the use of an incorrect/incompatible tube type. If you are unsure of what tube or tubes your equipment uses, consult the manufacturer before making a purchase. Using an incompatible tube type may cause severe damage to your equipment and will void your tube's warranty.

  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.
