This new old stock-testing Raytheon 6L7 tube was tested on our Paul Hart-calibrated TV7/U for shorts

WE CANNOT GUARANTEE FOR FAILURES

I just cleaned this LP on our VPI 16

One is a Cunningham

double-side getters and and absolutely no flashing -- somewhat-disconcerting

It measured 58/56 where minimum (65%) is 40/40 and 100% is 62/62

This lot of four Tung-Sol 6AC7s was tested on our Paul Hart-calibrated TV7/U for shorts

new in box (for Tube One) matched pair of GE-MANUFACTURED 12SL7 / 12SL7GT dual triodes was tested on our Pau Hart-calibrated TV7/U for shorts

They have G 5R and G SR date codes

The Bottlehead calls for a 12AU7 which is a pretty-different tube

top chamfered solid-O getters and two additional vertical support rods for increased rigidity and lowered microphonics

where minimum (65%) is 36 and 100% is 55
