how are they hf interference wise?? I put a ice tvi filter in front of
it but still get a little tvi on 20m on older tvs and a ton on 10(all
sets)

think an additional filter after the amp might help

Might also try filtering the AC power line cords. It's not unusual
for TV sets to suffer from RF incursion through the power supply.
Adding a ferrite or two to each set (one on the power cord, on as a
common-mode choke for the coax from the distribution amplifier) as
close as possible to the set may help.
