a Sylvania Factory matched quad!
NOS NIB NEW USA
pro tested
You are buying 4 tubes, known in the jukebox community as "6973-sub" tubes, designation "6CZ5".
This is a Sylvania FACTORY MATCHING QUAD, "ER DHE" code on each tube, complete with original 6CZ5 sleeve!
These tubes will work in your jukebox amp that uses 6973 tubes, as long as you jumper together "pins 1 and 8" underneath each 6973 tube socket. If you make that VERY easy mod, you can use these tubes and still use original 6973 if you want someday. If you are not comfortable doing this mod yourself, any respectable amp technician will be glad to do this for you.
Why you want these tubes:
- factory matching quad "ER DHE" code each tube
- GRAY PLATE construction
- electrically matched for cathode current
- NOS NIB NEW Made in the USA
"6973-sub" tubes have more than 30 years of being used in jukebox amps with excellent results.
Of course, your amp must be properly rebuilt by a technician before ANY tubes will "work" in your amp. Therefore, if your amp has not been serviced and you expect new tubes to "fix the problem", then please understand that "it doesn't work that way."
Verified testing strong with our professionally calibrated B&K 707 mutual conductance tube tester, and without shorts or leakage.
NOTE: these tubes are for JUKEBOX AMP USE ONLY. These are NOT advertised as being compatible with guitar amps or anything else.
