[Amps] SB-220 low output on 10 was: SB-220 input problem

[N4ZR]

I'll be ... I don't understand why, but putting 8-10 feet of RG-8X 
between the K3 and the amp brought the input SWR down to ~1.5:1.  I'd 
love to know how come.  Power output is still quite low (~600W.)

Could be these 30-year-old 3-500Zs are finally wearing out.  Does that 
normally show up on higher bands first?
