I came acrose this pdf of old hifi ads from the 1970's - lots of hifi kits and so on.
Nostalgic reading for those of us who used to hang out at Laskys and trawl through the ads in hifi mags.
Makes interesting reading (for some of us!) with historic pricing. E.g. Comet were selling a Garrard SP25MkII for £9.95 ,a Garrard 401 for £27.45 and a Goldring GL75 for £28.95
Boots were selling hifi systems.
