Transformers made for Leslie amps were built by a company called Triad in the 60s and earlier, lately Hammond-Suzuki produces leslie amps using hammond-suzuki transformers. A guy I know from chicago takes old triad transformers and replaces new Hamsuz transformers with triads and gets amazing results. Im looking to try something like this and purchase triad transformers but I dont know how to find that info from a schematic, as far as which types of transformers to use as a replacement. anybody irritated enough to explain that to me? Thanks.
