Valve amp. informations?..

Hi.. i have few of old working valve amps. also has several valves.. i know basic power supply and building concepts of valve amps. even i made some amps. also
I need some links contains schematics and information about valve amps. specially 6SNGT, EF86, 12AX7, 6922.. If anyone knows, let me know..
(one more thing, even in the digitalized world i love listening music from valves thats why i need..)
thanks.

Just google, there are many, many sites with valve/tube schematics - they are really very simple and crude as well.
