[QUOTE="fredeb, post: 1115659, member: 13623"] Regarding price discussion earlier in this thread , I am unfamiliar with the Miniwatt amps , or cheap Chinese amps , but I have to wonder about the quality of iron used in transformer laminations and the quality of wire used to wind transformers . Is it even copper used ? More likely aluminium enameled with copper coloured enamel . I know for a fact that transformers wound by Karel use high quality (and very expensive) copper and high quality grain oriented steel laminations for core . Other than these qualms , It seems insane to compare a mass produced cheap amp to a custom-made amplifier with hand-wound quality transformers , purpose built by the amplifier builder who has many many years experience in valve amplifier building and transformer winding . One can't make the transformers (a pair of output , and a power transformer) from decent materials for the quoted price (~$300) . Not all tube amps (of the same spec) are equal . You get what you pay for , in this case at least . [/QUOTE]
