Echolette was German manufacturer of electronic amplifiers and effects units. The company was founded in the 1930s by Arthur Klemt. The business was sold to the Dynacord company in the 1980s.
The original amplifier had so called DIN plugs (1958) as inputs, after 1960 they changed to jacks. The Beatles used this amp, rated at only 40W. Maybe they brought it with them when playing in Germany on the Reeperbahn?
Sounds much like an old Fender, just not as sought after. According to some it was based on the same reference amplifier (found in a tube manufacturers handbook) as a Fender that was sold 2 years later.
The M40 uses 2 x EZ81 (eq 6CA4) rectifier tubes, 5 x ECC83 (eq 12AX7) tubes in the preamp section and 4 x EL84 (6BQ5) tubes for amplification.

Was often accompanied by a tape echo called Echolette NG51-S.
