and of course, while getting away from cheapest, there are a few neat tricks. One to reduce the output Z of the first stage while simultaneously reducing noise: parallel sections of a twin triode.
This offers a few neat opportunities to pull from developed circuits, and make further improvements.
and I am already getting away from a 'Cheapest sol'n', heh-heh-heh...
Long skinny chassis, PS at one end, and amplifier at the other. Guinevere style plate loads on the final stage so it can drive a reasonable load.
Parts are sure cheaper than for a big, high power amp, yes? cheers, Douglas
