Serial number 20328
Portable Transistor radio Made by Hacker Radio Ltd, Maidenhead UK. The radio which was kindly given to me by Stephen Trilvas is housed in a blue leatherette covered wooden case and unusually is a VHF only receiver.
This is a high quality single band (88-101 mHz) radio with 13 transistors, treble and bass tone controls, sockets for a tape recorder and external aerial, automatic frequency control and inter station muting buttons. This radio is normally powered by two 9 volt PP9 batteries in series though as can be seen this one came with a power supply.
I understand that this model was first produced in 1969 but the date codes on two of the electrolytic capacitors indicate that they were made in 1967.
