The good people of Apugland might know this already but Firstcall Photographic now stock P3/4 ES enlarger lamps. See here - http://www.firstcall-photographic.co...-enlarger-lamp These are the 150w opal jobbies that I've never been able to find elsewhere. I am informed that they're probably Chinese in origin (phillips having stopped making these some time ago) but anything's better than nowt. They're a handsome fiver apiece and they've got plenty in stock, or so they tell me! Regards, B.
