Yaesu: Yaesu FL-2000b high input SWR on 10 and 20m

[Champo]

I have a Yaesu FL-2000b that works other than the input SWR is high on 20m and in outer space on 10m. I was able to get 80m, 40m and 15m all below 2:1. 20m I can't get below 3.5:1 and 10m is so high it's hard to tell if it's 6:1 or more. I've focused on 10m so far since it's the worst. Both of the 100pf caps are good. I also replaced the Chinese tubes that were in it with NOS Cetrons in case it was tube related with no change. I tried tuning it on 30, 29, 28 and 27Mhz in case it had been messed with snd was no longer centered overthe middle of 10m. The factory adhesive that kept the slug in place was still intact on all bands but 10m. It had some issues when I acquired it. Also the band switch is clean as a whistle. No burnt contacts on the front or back of the band waffers. The coil/slug tracks with the 15m slug when the caps are removed as well and a VNA is used. Any help/ insight would be greatly appreciated.
