PERDIO 'CONTINENTAL' 1959-1960, three-band portable
A transistor set - though the case is big enough to accommodate valves. This is really a two-band set - the third band is a marginally-useful 'trawler' band and I can't actually get anything out of it. It has 2*4.5 volt inputs (I converted it to run on 'C' size) and germanium transistors. It's only really a few years into the 'transistor' age. Sound is fairly good but surprisingly light on bass compared to the Hacker Sovereign, which is similar in size - and also to the Defiant A55, which is actually smaller! This set has a thin plywood case and a cloth front, and a tuning dial rather than a cursor. 'Perdio' was a portmanteau of 'Personal radio'. The brand only existed for around ten years.
