I recently purchased ( from John ) a chassis with 2x Sansui 1000A OPT's , 1x Sansui 1000A power transformer with RCA plugs , Binding posts , Bias pots and measuring points and some sockets fitted . Transformers do not have UL taps and power transformer taps are 190V , 32V and 3x 6.3V ; primary taps are 115 or 230V . OPT's are 30W specimens designed for 2x 7591 @ 420v on the anodes . I'm guessing then , that the OPT's are wound for a ~6600K plate to plate impedance , my guestimate coming from the 7591 datasheet specs for UL PP specs .

Can anybody please help me figure out what plate to plate impedance the OPT's are set up for ? Secondary taps are rated at 4 , 8 and 16ohm on the schematic .

Also , I wondering if it is possible to get 30W output from any power tubes in triode or pentode mode without using a voltage multiplier , but using ~280VDC B+ from solid state rectification ?  Could I get that from 2x 6L6's ? Any suggestions and thoughts welcomed . What would you do ? 

7591 datasheet http://tubedata.tigahost.com/tubedata/sheets/168/7/7591.pdf

I'd like to use both triodes of a 6N6P ( ~E182CC ) as drivers for output tubes , and perhaps another 6N6P ( or 6N1P or 6N2P ) for gain and phase-splitting .

Schematic provided for idea of transformer components .
