Philips battery powered portable tape recorder, model EL3302 with microphone, earphones, bugging coil, and 2 carry-cases, 1956-1963.
The EL-3302 was a mono compact cassette recorder made by Philips. Manufactured to a mass volume and produced in many countries, the majority of the earlier units came from Austria. This was a player and recorder, with built in erase bias for a separate erase head providing high quality audio reproduction from compact cassettes. It has a full range of tape control features including fast-forward, rewind, and play. The pause function was a switch on the microphone, which simply cut the power to the motor.
The DIN sockets provide audio input/output facility, external microphone connection, and mains adapter facility. The internal speaker was very small, and the manufacturers thoughtfully provided a 2-pin socket to connect a better external 8 Ω speaker.
The unit is only 20 cm × 11.5 cm × 5.5 cm in size and packed with electronic and mechanical engineering. Removing the plastic shell reveals a metal die-cast chassis. The tape transport mechanism and control linkages are metal and reliable. All the pulleys, and drive wheels, including the capstan flywheel are metal.
The internal circuitry, built on a copper-clad printed circuit board, has a rich assortment of components. The component density is high, which is why the resistors are in an upright position. The circuit uses ten metal-tube germanium transistors, which are AC12x series. There are two transistors in a "Class A" arrangement form the audio power output circuit, whilst five transistors form the record/playback circuitry.
The unit also houses a small separate PCB consisting of a two-transistor circuit, which forms the voltage and speed regulator circuit of the capstan motor. The earlier models of this tape recorder did not have the speed regulator, and this appears as a later addition. Five "C" sized dry cells, or an external 7.5 V adapter powers the unit.
