Hi there,

I've read in a recent topic about using from 50 to 200ohm swamp resistor in
a 4CX1500B amp.

What would be practical benefits about moving from 50 to 200ohm?

Would less driving power be needed  as  voltage is doubled?

Do you suggest any particular toroid and turns value for having a smooth
and broad response curve from 1.8 to 30MHz?
