Description
Philips Holland production of the fifties!
This is a pair ECC82 produced by Philips Miniwatt in the fifties in Heerlen the Netherlands. The tubes have a D-foil getter on ‘silver’ post and long ribbed grey plates (version k63), see pictures. Very healthy tubes with NOS specs! Tubes with matching systems; see test results.
Sonics
The Philips Miniwatt ECC82 of the fifties is highly regarded; deliver crispness, 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!
Note: if your system is to “bright” already, this tube is not a first choice. ECC82 tubes of Mullard, Brimar or Telefunken are to be considered in that situation.
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.
