Welcome to the "Smarvo club"
For some reason I can't access anything but the first page of my threads, but there's the schematic for the Fame
pre-amp which only differs on couple of components on the mid-control section.
The way I read the negative comments about the E300T is that people were POed by the fact that they were fooled to buy an amp for twice the price just for the Eden badge. And the Eden rep's insisted to the end that it was in fact a genuine Eden designed amp that just happened to be manufactured by a company located at the Far East.
You won't find many negative comments from the Ashton and Fame users, they pretty much knew what they bought and expected accordingly.
OTOH, the people who bought the E300T's at a "discount" (for roughly the same price as the Ashton and Fame
) have been pretty pleased with theirs.
