Thanks Dmans,
there is a coil in series with the input to the cathode which is why i was trying to add the trimmer off of it to ground. Its that .75uH coil in the schematic.
it seems like not having that 47 ohm resistor in circuit is messing with the tuning, and im starting to think that could have something to do with the long coax run to the switch.
it runs from one side of the front of the amp to the other, and the ground is established by the switch itself. that means that when it's not grounded at the switch, there is a long open cable run in parallel with the input to the cathode.
im going to try some oddball things like adding the cap after the coil, or figuring out a different way to switch that resistor in.
im also thinking that the notes on the schematic may be because the amp may have been made for 10 or 12 meters and there were "secret" instructions sent with the amp to make it work on 11 like was done with the kenrich and other amps.
i'll be sure to post whatever i try, but it may be a day or two as i think i just need to think and read before digging back in to it.
this thing was such a wreck when i got it, and it has taken so much work just to get it working as well as it does right now that my brain just isn't in to taking things apart again yet LOL.
