In Reply to: What brand ECC 81 is this? posted by steve.kaelin@comcast.net on January 2, 2015 at 14:05:46:
Tube you have is RFT East German made.
To our knowledge, Tungsram Budapest Hungary did not make ECC81 tubes. Most Tungsram ECC81 tubes are relabeled RFT/Funkwerk.
British Tungsram did relabel French Mazda 12AT7 tubes (see link below)
