|Clarke & Smith Model 8812
Return to The Boatanchor Collection
|This unit is basically a 12 watt
mono amplifier, powered by an orthodox arrangement of the
venerable EL84 as a push-pull, with an AM/FM receiver
attached. It also has inputs for microphone and
record-deck (or 'gram', as it is called) and the ability
to transmit the output over a 70V line.
Clarke & Smith manufactured a range of equipment that was, "Designed in consultation with certain Education Authorities and approved by the Schools Broadcasting Council of the United Kingdom". The glorious Socialist state that was England between Macmillan and Callaghan decreed that the BBC should stand fast to it's Reithian ideal and provide a School's Radio Service to educate the children of the masses.
The Model 8812 Receiver was 'designed to meet the needs of medium sized schools' and was capable of feeding six extension speakers simultaneously - a small monitor speaker on the front of the unit being able to allow the 'programme controller' to listen in.
Built to 'battleship standard' it is very heavy duty and exquisitely precise in it's internal layout and wiring. I have included it here as a fondly remembered example of the kind of gear our taxes purchased (well, my parent's taxes) for use in the schools of the 'New Jerusalem' that England tried so hard to be in the 1960's.

Postscript: Clarke & Smith diversified in to many areas in the 60's and 70's. Frank Clarke, the founder, was actively involved until his death in 1997 but the company is, unfortunately, no more.
