I don't doubt this is the optimum solution, but necessary?  My TS-930 is 
perfectly happy driving my unmodified SB-220 on all bands including 12 and 
17 meters.  My Mark 5 is happy with it on every band but 40m, where the 
power folds back a little because of the input SWR.  Again, it works fine 
on 12 and 17m even though the input circuits were never designed for these 
bands.
