The ARCO 420 and 460 series of mica trimmers work well up to 125 and 200W
respectively when used as input network tuning. I have not ever had a
problem with them in an amp but would not consider them high current
either. Voltage ratings are in the 350-500 range so I would not use them
in an ATU except at QRP.

The 300 series will handle somewhat more but are hard to find.
