I just got a 422B. It works great and makes the 1200 watts predicted in
the manual at tune up. The voltage interpolates to 2800. I suspect
this is lower than actual. I wonder if anybody has replaced those pots
with high quality multi-turns? Heck, are those even available anymore?

One has to interpolate the marking and space between the numbers. Thus
there is 800 volts between the 2.4 and3.2 or 2400 volts and 3200
volts. Then 1/2 way between the two would be 2400 + 400 or 2800.
Then half way between 2800 and 3200 would be 400 volts or 2800 +200 =
3000. So 3100 would be slightly above the 3000 volt value.
