It's time for another rectifier pic.
RFT (Rundfunk-und Fernmelde-Technik) manufactured this AZ12 in Röhrenwerk Mühlhausen, a state-owned factory in East Germany in 1952, during the Cold War. After the WWII, RFT took possession of a number of vacuum tube manufacturing facilities previously operated by Telefunken, Loewe Radio and others. This tube was manufactured with old Loewe Radio assembly line equipment installed in an old Lorenz factory building located at Mühlhausen. And thus, the construction strongly resembles a Loewe Radio AZ12 and the sound is also very similar.
Great info Ken.
This looks to be an AZ12 mesh plate, very nice.
