JJ Electronic OEM KT88 6550

This product is currently out of stock and unavailable.


These JJ KT88s are OEM for use in new amps so they do not have the JJ label or come in a retail box. They are 100% JJ and exactly the same tube as the labeled, boxed tube but for less money. The label does not enhance the tone one bit!!

The KT88 is a beam output tube with a power output potential of 42 watts. Awesome power and tone. It can also be used in 6550 amplifiers.


Tested on the RoeTest professional computer testing system.

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