Nothing to do with FLAK.

ELA K is not FLAK

This is Telefunken microphone amplifier, civilian stuff.

[csmagdo]

The ELA abbr. comes from Elektro Akkustik, a brandname of Telefunken (doughter company of Siemens and AEG, founded in 1903), the welknown Telefunken ELA M 250 and 251 micros sit in this series as well. They are told to be the best sounding micros ever

It is a loud hailer, and as far as I can see indeed a civilian type. The use of civilian tubes, open use of the Telefunken logo and absence of any military stamping or tagplates point at that. From the tagplate I gather that it was manufactured in 1941, construction and design seem 1940's so I do believe it is a wartime example. Should be fun to operate, but I would get somebody competent to check out the electrics before plugging it into the mains.

Amplifier: The both of EBL21 (replacement of original EL11 tubes) are Czech post war (TESLA) provenience.
Suppose the device was operated/serviced in Czechoslovakia withinin 50-60th years.
