I can't advise you on the binocular cores for transformers, but W8JI's website is an excellent resource for that. See w8ji.com There is extensive advice on suppression cores (for killing common mode noise), as well as lots of measured data on chokes wound using those cores, on my website. http://audiosystemsgroup.com/RFI-Ham.pdf > 2.Do Fair-rite send small quantity to private persons? No, only in rather large quantities. But they have an extensive network of worldwide distributors, listed on their website. Some may be a lot more user friendly than others. I've heard from UK hams that Farnell, the UK distributor, is sinfully expensive and carries a very limited selection of Fair-Rite parts. I've seen suggestions that things may be considerably better in EU outside of the UK. Appendix One of the link above summarizes data and part numbers of useful parts and known good US distributors. I don't know which, if any, of them will export to LA7, or at what cost. Another reminder that it's worth pooling orders with other local hams for commonly used parts like this that are otherwise hard to find and expensive. Parts are always much less expensive in quantity, and the costs of shipping 50 or 100 pieces is much less than 100 times the cost of shipping one. 73, Jim K9YC . _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw?
