Rerurn to Romy the Cat's Site

I decided to try build amp by myself but I will need some help...

First, the parts...

1. OPT transformers- I posted mails to:

Tribute, lundhal, intactaudio, ae-europe, and today to promitheusaudio

I ask them for transformators that Romy mention somewhere on this forum:

 "8 or more secondarys, 8:1 in the middle mapping, DCR primary > <50R, 350mA amorphous"

I got answers from lundhal and intatctaudio.

lundhal proposition is  LL1693/350mA but it cant by amorphous

He can make amorphous  LL1627

intactaudio asked me a question:

"I do not like the procedure of "remapping" the secondaries since it 
forces compromise. I can do it, but would need to know what the 
"preferred" decondary load would be"

So what should by decondary load?

Best
