It says that the 3 db cutoff frequency is 43 MHz, and that it is
especially useful for Channel 2 and 5 interference. It also says
it is rated at 1000 Watts, but it looks more like 500 to 600 Watts
realistically. $18

TUBES - 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.
