What web-sites have scematics for SET amps ?

I am trying to find the diagram for Fi 2a3 amp so I can do some repairs....Anyone know about the web-sites for tube amp diagrams ??
I don't know about the Fi. Try looking at the database at www.duncanamps.com. They have tons of stuff.

Or for another 2A3 schematic


Try here and see if you can't find s/thing. Check the links too.
I have tried those web-sites without any luck , but I am still looking....Thanks for the help ......Will
