Electro Harmonix EL34H Power Pentode Vacuum Tube



New old stock Power Pentode Thermionic Valve. This EL34 is electrically a Mullard EL34 power tube. A staple during the ’60s, the Mullard EL34 was the standard tube in the classic British tube amps of the era. This precision made power tube can take your sound back to that golden era, especially in a Marshall, Hiwatt, Orange or similar amp. Made to exacting vintage specs and tested for quality, this EL34 power tube delivers that sound you want from your amp. These are the slim EL34.

Tested on the RoeTest professional computer testing system.

Matched sets are matched by plate current and transconductance using the new Maxi Matcher 2
