Basic Circuit for direct heating triode amplifier circuit .i think you can use any kind of
direct heating valves instead of SV 811-3 .I tried 2A3,300B,PT 15 and SV811-3 .even you can
use EL 34 indirect heating valves. depend on adjust grid bias and plate voltage.

in Chile early 2002 .out put transformer are 2.5 Kohm 20W rms.this time I got around 6W rms
Max power under 2A3 Sovtec mono plate. but RCA 2A3 is Best sound.
