The funny thing is I actually got this Spam in my email the
day after aquiring a 250 Watt Johnson Matchbox exactly when I
was wondering if I should have got the 1000 Watt instead. The
spam said "Is your johnson big enough?" and I wondered how
the heck did they knew I was thinking about that. Turns out
the spam had nothing to do with ham radio, wink wink, nudge
nudge, know what I mean?

Only thing is the KW Johnson is rather inflated pricewise
these days. I am trying to stay within a budget. I understand
that since the 250 Watt Johnson was used for AM that it could
probably handle 600 Watts of SSB or even CW, this is what I
have seen posted by perusing through Google searches. What
are the limits powerwise of this smaller Matchbox? If I want
to think about a linear amp, I may want to know my
limitations with the smaller matchbox. Are linears such that
you "select" how much power, so even if the linear is capable
of more than the matchbox, I could experiment to see how much
the matchbox would handle. I apologize for all these newbie
questions. Maybe a Collins 30L-1 would be a good companion to
the matchbox...

I use one (250-watt) at 600-watts key down without any problems.

That's going to depend to some extent on the characteristics of the
load. Very low, very high, or very reactive loads can be difficult
for a tuner to handle - they can result in high voltages (the
capacitors or the output connectors may arc over) and/or high
circulating currents (high losses in the inductor, leading to
heating). A tuner might misbehave into some loads, at power levels
where it'd have no difficulty at all into easier loads.

of more than the matchbox, I could experiment to see how much
the matchbox would handle.

Depends on the design. Some may have adjustable gain, some may have
an adjustable input attenuator. Others are fixed-gain and you'd need
to reduce the RF power output from your exciter/transmitter in order
to make a proportional reduction in the linear's power output.
