In order to understand MFJ products, you just need to know that many of them are rated in
"MFJ Watts."
An MFJ Watt is about half a regular watt. So a "1500 watt" MFJ tuner is good
for about 750 normal watts.
They are also living somewhat in the past. In the Old Days when US hams were
limited to 1
kW DC input to their finals, a good class-C amplifier might make about 750
watts output.
That was the legal limit. And that is about what their "legal limit" products
are capable of.
Having said that, Ameritron amplifiers -- at least the tube amplifiers -- are good buys
and deliver as promised. They are not top quality, but you get what you pay for.

well. He
has a linear, but it only puts out about 350 W PEP. The legal limit here in the
UK is
only 400 W PEP, but I know his linear is not capable of 400 W - or at leasat he
never
pushes it to 400 W. But despite running an ATU at 35% of its maximum power
rating,
something has burnt out in there. I forget what it is, but it has resulted in
him
turning a shaft around on one of the tuning controls, as something has gone
wrong in
there, which meant he got RF burns on the tuning control.
