If only the junk today was made like these... 
I have one and it handles 500 watts easily.  Tune it at low power and get a 
good match and it'll handle more power than the tuners available today.  These 
were rated for AM service so they can take quite a bit more on CW & SSB,  I 
never used mine for RTTY.

I just purchased a 275 watt Johnson Matchbox, almost mint condition.  They 
are rated at 275 watts, but the components inside look pretty hefty.

Has anyone ever run more than 275 watts into one of these?  I've built 
tuners that didn't have parts as husky as this one and ran quite a bit of 
power through them.

My SB-200 puts out about 500 watts on most bands.

Just curious.  73
