6CL6 tubes For Sale: 6CL6 tubes For Sale:
-
I found a stash of 6CL6 tubes. These are NOS.
-
The 6CL6 is used as a driver tube in some of the
hybrid rigs, plus many of the older vintage rigs.
Many have found that low power output in these
rigs is due to a weak 6CL6 instead of weak finals.
-
Buy these for only $8 each, plus shipping from Florida.

Eimac 7580W / 4CX250R: Offering this from recent estate tube lot - cosmetics indicate either NOS or very, very low hours.
( Taken from Eimac Spec Sheet ):
The 4CX250R/7580W is designed specifically for use in Class AB1 linear amplifiers where shock and/or vibration preclude the use of non-ruggedized tube types. The 4CX250R/7580W will deliver more output in most linear amplifiers which presently employ the 4CX250B.
My TV-3B/U tube tester doesn’t cover this one, so it’s sold As-Is / No Return.
