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.
