Hello
The volume on my 38-2 seems low. I need to turn it up about half way to get normal volume. The data sheet for the 6F6 tube using PP Class AB (Pentode) Fixed Bias shows max 250 volts for the screen, 375 max for the plate and -16 min for the grid. My plates are 220 volts, screens 230 volts and grids -13.5 volts. Is the grid voltage too high? Looking at the schematic I can see why the screens are higher but should they be?

Thank you,
Dan
