This was a single speed,
half-track mono recorder with a 5″ reel capacity.
The EL 3527 had an amplifier output of 2½ watts and a 4″ circular
speaker which could be used as a straight-through amplifier system.
The microphone, radio and pick-up inputs were mixable and outputs were
provided for external amplifier and external speaker.
An interesting point to note: this was one of Philips first recorders
to utilise a printed circuit.
