Lightly used, like new, batch of 2 tubes, NOV-1971 Original TESLA Military Production ECC802S - Replica of the famous Telefunken ECC802S tall plate with flanges. Non-corrosive alloy pins. Made by Rožnov n.p. závod Vrchlabí. Produced in former Czechoslovakia (now Czech Republic). EC802S is a Premium version of 12AU7 ECC82 with low noise, and low microphonics. These tubes are very quiet and musical.

Construction seems to be a copy of the Telefunken ECC802S tubes with tall plates and rectangular flanges on the plates (by no means an implication that these sound exactly like the Telefunken ECC802S). Also the Identical in construction to 1960's Tesla Long Plate ECC803S variant.

Tested and matched on Top of the Line Calibrated Hickok 580 Lab Grade Tester recently calibrated by late Chris Haedt. Average Brand New Tesla ECC802S from 1960s-70s test in the 2500-3000 mmhos range on this tester.

NOTE: Test scores are not close to make a matched pair. Triodes within the tubes are well matched.

Test Scores: 2700-2600, 2250-2150 mmhos.

$60 for this batch of 2 tubes as shown.
