Description
Tungsram ECC82 This tube is made by Tungsram Hungary. It has gray plates with copper grid posts and a halo getter.
The tube has excellent test values that match the factory specification very well and a balanced system.
Test method
Mutual transconductance, plate current (tested with Ua= 250V, Vg= -8,5 V), gas and shorts tested with: AVO CT-160 (Dutch army tester), Utracer3+, AVO Valve Data Manual 23rd edition 1981, Philips 1532, RFT stabilised power supply and 2x Keithley 2700.
Test results*
The measurement data below show that the tube is matched and balanced. And fully in line with the factory specification.

* Specified measurement data
I give no guarantee on measurements or different values measured on other tube testers or analysers. Just in case of mismatch of “standard” values of the different tube testers “standards”. My test results refer to tube data sheets provided by the original tube producers. (You’ll find them easily on the web.) And are measured with the specified test equipment.
