Echolette
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.
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
