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.

Thanks. 73,

Dead 3-500 Tube For Sale: Dead 3-500 Tube For Sale:
-
I have a dead 3-500 tube available. It
no longer functions as an amplifier, but
the filament in it is good, so it could
be used for making a lamp, or any other
place where only the filament is needed.
Buy it for only $12 plus shipping from Florida.

FS - 4 of 845 Tubes, NOS Unused: FS - Qty 4 of 845 tubes, NOS and unused.These tubes are from a broadcast transmitter service company stock. They are in RCA labelled boxes and the tubes are stamped "RCA Made In Germany". There are no other markings on tubes. It is believed the tubes are Chinese made. However, all 4 are identical and have tested good. One test was done on a calibrated Hickok tester (used by a tube buyer) with adapter. The other test was an idling test using a regulated plate and grid voltage supply. Tubes were idled at 403 vdc plate, at -50 vdc grid the plate current ranged from 86-96 mA. All four tubes for 400.00 plus shipping.Thank you.; Listing #1732371 - Submitted on 06/09/25 by Callsign W5FH, Web Site: https://www.qrz.com/db/w5fh - IP: 74.231.123.36; Click to Contact -- Click Here to View Picture -- Send this Ad to a Friend
