Note: Tube tested on my SENCORE TC162 MIGHTY MITE VII tube tester. Tube read strong good: 1st plate @83, & 2nd plate @80 where bad tube reads below 50.
Just FYI: please see the images to compare with one BRAND NEW in BOX (NOS, NIB) Mullard 5Z4G tube which read ~@85 on my tester.

Also tested in my ALTUM SET mono block (designed for 5Z4G or 5U4, 5U4G, 5U4GT tubes) with excellent result and the tube sounds fantastic.
