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.

but not IN the studio. the newer solid state stuff is a lot quiter but still
has fans running.

have you noticed that as power amps are now being made bigger and bigger
that there are now speaker systems bening made that claim to handle the
power? for example the peavey QW series.
