Hello,
to source funds for new projects I reluctantly part from these beauties....
These are O getter Mullard UK made NOS E88CC. Got them in a bulk package so they don't have original boxes, however they have the same production batch 7L1 R8F1, gold pins and were tested on a friend's russian top-notch tube tester (LL-3 IIRC).
The read values are on the picture. The tube tester setting indicated as 100% for the E88CC 12mA emission and 11,5 ma/V conductance.
Similar items go for $$ on ebay, reasonable offers on email.
Cheers
Andrea
