 30th May 2007, 02:02 PM #3 then_dude   diyAudio Member   Join Date: Dec 2003 Location: brussels aha, this is indeed something which i didn't forsee; that looks promising. so allow me to pose another two questions 1)so it would be capable of putting out 380ma at AC current ? cause it will always be used as ac current; 2)now it puts out : 140v at 380ma, after the power trannie there is a voltage doubler. the trannie itself has two primary's 0-115 and 0-115. so there is a switch for 115-230, it depends how you wire it; but let us now suppose, that i want to get 280 immediatly out of the trannie: that means that i could connet 0-230 on each of the 0-115v . that would mean that i get 280 volt at 190ma, and also that the 6.3 voltage would end up to be 12.6. (but i could wire some heaters in serie: although that would maybe a sonic problem) but as long the trannie can hold up with the high voltage, in terms of electrical shortcut through the paper it would do fine ? or am i wrong on this one ? thanx a lot greetings
