2 NEC EF86 6267 tubes tested NOS

pair of vintage NEC 6267/ef86 tubes

these are new old stock tubes that came in a manila envelope from kodak to a repair shop. i personally removed them from their original packing.

no manufactures code on these. the both have 4X on them which may be a date code. i would guess these are made in japan since all the nec stuff i have seen is japanese. they have 1 top seem
