Notes:
(OB) = original box, (rb) = relabeled/replacement box, (wb) = white box,
(L) = loose (no box), (pl) = paper label on tube (original or third party)
(H) = tested on Hickok 539A
ST=ST Style, TT=Tall Tubular Style, GT=GT Style, JAN = Military
Emission Strength = Percentage of emission measured on Eico 666 tube tester
(Emission Strength = 100% baseline reference, >80%:good, >60%:fair >40%=diode good).
Gm = Mutual conductance measured on Hickok 533 tube tester; Except (H)=tested on Hickok 539A
(Gm = measured/baseline, measured1:measured2/baseline, measured1:measured2/baseline1:baseline2).
