6AC5 Single Ended
Just tell you very simple circuit,if you can get for diver
of 6AC5 is 76 and 6P5 better than 6CG7 Noval.because 76 and 6P5 has
grid bias.at 250 V plate voltage.so you can get easily into 1st grid of
+13.5 V.you can get very sweet sound like a RCA 45 .out put transformer
7 k ohm
or 5 k ohm.circuit is indicated next.
