NOTE: From the same lot of Item 970 except these test about 20-25% lower than an average Tesla ECC802S from 1970s.Brand new, Matched Pairs MINT NOS 1974-75 Original TESLA Military Production ECC802S with LOW SCORES - 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. In white boxes from bulk pack.
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 Hickok 752, just recently calibrated and modified
by Hickok expert to all Solid State to eliminate drift. From our
experience, an average Tesla ECC802S from that era measures between
1450-1700 mmhos on this modified Hickok 752.
Price = $60 per Matched Pair.
