Swan 500 500C 500CX 6LQ6 (2) + 6GK6 driver tube set
Late 500, 500C, and 500CX which used 6LQ6. Note early 500 used 6HF5 and they are available in my store with driver.
Pair of Matched set of rugged 6LQ6 (2) and a 6GK6 DRIVER tube. Test better than new on my tube tester and should work great in your ham rig. Put new life into a great radio like the Swan 500 (6LQ6), 500C, 500CX with this new set and start working DX again!
For best results remember to always replace your driver tube and neutralize your finals when putting in new tubes.
Important Technical Note: Swan used terminal 6 of the 6GK6 tube as a terminal strip for connecting a 100 ohm resistor and an RF choke in some radios. Unfortunately the newer 6GK6 tubes also use pin 6 connected internally to the screen of the tube. If you plug in the newer 6GK6 tubes into an older swan using pin 6 as a terminal strip, it will destroy the resistor and choke!
You will need to check pin six of the 6GK6 socket and remove any components from that pin and reconnect them to a new terminal strip. Then plug in the 6GK6 tube and your driver should put out full output.
