Description
Early ECC82 pair with D-foil getter and long plates for the best possible performance!
This pair of ECC82 is produced by Philips Miniwatt in June & July 1958 in the Philips Miniwatt plant in Heerlen Holland. The tubes have a D-foil getter and long ribbed grey plates (k64 version), see pictures. Very healthy tubes with NOS specs! Tubes with matching systems; see test results.
Sonics
The long plate k64 ECC82 of the fifties (like the other long plates from the fifties) is highly regarded; transparency and a holographic sound stage. I refer to the many threads on the web for more information. Excellent preamp valve, low noise, very smooth extended highs, very good in phono stages. Balanced and smooth sounding with liquid midrange, recommended! In addition the long plates ECC82 tubes are recommended for their slightly warm signature.
Test method & results
The tubes have been tested carefully with the official Telefunken test set-up and our sophisticated test equipment. Please read our testmethod for the ECC82 tube family. The measurement data below show that both tubes are matched and balanced. And fulfill the factory specs of a new/NOS tube.
