Thanks, the voltages on pins 3 and 8 (cathodes) of the input tube are too high. I assume that the amp works but is sonically "thin" sounding and has less gain that it should. The obvious thing is to check the values of the resistors on those pins, as well as the values of the plate resistors (pins 1 and 6) to be sure they are the correct value.
