thanx
0.33c/w . maybe my 8 heatsink only sink 400w per channel.
i think i should sell them on forum. but these transformers weigh 16kg.
from china i post them to foreign country, i think post fee is more than
price of these trnsformers

in china less people diy hifi,specially solid state diy, only someone play tube amplifier. well,well, i do a try.
HPetter 's word encouraged me, maybe is good idea.
while talking about transformer, i got a question. in hifi design, is industrial
power transformer ok for it. whether or not need special design of transformer? in china only big factorys produce transformers, but they are for
industrial application .
