Use a pair of 4CX1500 (or larger) tubes. ;-)


3CX2500F3 even?... problem is the forced air cooling is so noisy.



Not if you build it right. The fans are usually vented outside the
building when used for AM broadcast transmitters. I know of several
stations where the air cooled transmitter is close enough for the
operator to see the meters while they are ion the air, yet you can't
hear them in the control room.
