So, I was reading some HP BArney Oliver stuff recently...
a question I have, is what's the math behind matching a cartridge to a preamp, generally?
is it the formula here in the Barney Oliver pre-amplifier schematic the same that would be generally used in other circuits also?
it's the R1* formula, bottom right...
the resistor is just behind the cart in the diagram on the left...
