Additional Details

Description

The SP2 was a portable, half-track mono machine first released in July, 1955 and manufactured by Simon Sound Services of Portman Square, London.
The deck was powered by three specially designed Collaro motors and had two playing speeds, 3¾ and 7½ ips. Reels of up to 7 inches could be accommodated.
The output from the internal amplifier was 10 watts from a pair of EL84s and this was delivered to a front-mounted 10-inch speaker or an external speaker. A straight-through amplifier switch allowed the recorder to be used as a public address system.
