Telefunken ECC83/12AX7 NOS matched pair

Smooth plate diamond base manufactured W. Germany 1960’s. Same production code BCA01Wa. Originally purchased from parts connexion as a tested, matched NOS pair about two years ago, I used them for about 15-20 hours in my pre just to check them out (utterly dead quiet) and then stored them. Test results are visible on the boxes in one photo . No longer need them, price is plus shipping and please add 3.9% for Paypal fees. I will accept Interac transfer for Cdn. buyers.
