[QUOTE="Ampdog, post: 139379, member: 144"] And to still continue .... Since my last post I finally had successful negotiations with SJ Andrews Electronics (Johannesburg). There are at present 12 transformers and 4 chokes on order. Cost for those interested: 500VA C-core power transformer: R890; similarly for a 150W valve output transformer also wound on a 500VA C-core; R500 for a large choke on an E-I core. (These are not readily commercially obtainable as the design is for my particular requirements, so one cannot easily compare. Even if obtainable overseas, shipping cost would probably be prohibitive because of weight.) [/QUOTE]
