Description Technical Specs
 
Not to be confused with the current production JJ Tesla and Teslovak junk.

Brand New MINT NOS 1975-76 Trinec Production ORIGINAL NOS TESLA EF86 Square Getter tubes. From the old Czechoslovakia (currently Czech Republic). Tube internals seem to be sourced from RFT with evacuation in Tesla glass bottle. Flashing pattern on sides of the glass is in Tungsram style but these tubes are Tesla, not Tungsram. In generic white boxes from bulk. Labels are very fragile as shown in the picture.

Tested and matched on Dynamic Mutual Conductance Tester Hickok 752, just recently calibrated and modified by Hickok expert to all Solid State to eliminate drift. 65% = 1200 mmhos for EF86 on this tester.

Some of these came pre-tested for Ia from our source in Europe.

Single Tube = $35. Select 2 for a Matched Pair.
