Hi, as this is my first venture into tubes, I need your help again. I'm planning on ordering some NOS tubes from a guy for my new Chardonnay.
(1) New Mullard GZ34 NOS, NIB, Double Halo Getter, black, small base.
Factory Date Codes of f32 B2I
Balanced to within 1.4%.
Tested (62,61) on a TV7 tester where 40 is the minimum.
(2) Used Tungsol 6L6WGB brown base, made for GE.
Measured 80% of new tubes.
Are these any good?
