Matched Pair Ken-Rad 2C22 JANCKR2C22 7193 Vacuum Tubes Milspec Black Plate NOS NIB 6FQ7 NOS NIB Most don't test greatThis new old stock, new in box matched pair of Ken Rad JAN CKR 2C22 7193 milspec triodes was tested on our Paul Hart calibrated TV7 U for shorts, gas and transconductance. There were no shorts or gas. Tube One measured 60 while Tube Two measured 64 where minimum (65%) is 38 and 100% is 58. I have played them in my Radio Craftsmen RC 2 monoblocks (with adapters not included) and they sound outstanding. They are dead quiet when the CD player is muted
