There's no need for any mods in the three 425s I own. All three work 
fine on 17 and 12. I tune 17M in the 20M position of the bandswitch, and 
12M in the 15M position. To find the "right" tuning, start with the left 
hand knob between 2 and 3, and the right hand knob around 0. I tune with 
dits -- start out with 15-20W of drive to get close, then increase the 
drive and retune until you hit the desired power out.

Remember that for a triode, we always tune for max output, AND we retune 
when we hit the max power at which we want to operate.

Two of my 425s work on 30M, the other, the oldest one, I think, does 
not. And yes, I run 200W on 30M. :)
