In 1971 I built myself a hi-fi set up-(as you did in those days!) massive speaker cabinets,base filled with concrete, frame work air tight sealed, baffles, tweeters etc. (I was an avid reader of Hi Fi monthly) and I used to go to a hi fi shop on Park Row, checking out all the bits'n'bobs! Anyway, years ago I mounted the speakers in the upstairs windows of a shop I used to manage in Broadmead, and on Saturday mornings we would open the upstairs windows and blast out the likes of The Associates and Simple Minds. Guys would come into the shop saying they could hear us in St Pauls! Great fun until the cops arrived!
Anyway, I've still got the amp, the speakers I left in the shop (!) and I think the deck - Garrard SP25 mk11 - might be in a box in my loft (serious ammount of stuff up there), so Bernie, I'm gonna see if I can find it (mission for today).
