Matched Pair Cunningham 6J7 Vacuum Tubes Valves

This matched pair of Cunningham 6J7 tubes was tested on our Paul Hart-calibrated TV7/U for shorts, gas and transconductance. There were no shorts or gas. Tube One measured 24 while Tube Two measured 27 where minimum (65%) is 31. I have played them in my Musical Paradise 301 MK 3 with adapters (not included) as 6SJ7 substitutes and they sound great, even though they test poorly. WE HAVE SCORES OF THOUSANDS OF VACUUM TUBES. IF IT'S NOT LISTED, WE MAY HAVE IT. PLEASE ALSO SEE OUT ETSY SISTER SITE "LOWTECHTWOO" AND/OR CALL OR TEXT US AT 202-372-6931 IF YOU DO NOT SEE WHAT YOU NEED OR HAVE ANY QUESTIONS. 1.
