I agree with Rod, that the volume trouble is probably elsewhere.
One has to be careful with diode sub: you will have two processes that increase the voltage: 1) diodes have almost no voltage loss, so your rectified voltage will rise (and quickly so, so you might have quite a bit of inrush current, if turned on at the peak), 2) also due to the fast rise, your other tubes do not come on-line as loads, and so the voltage for a few seconds will not create any load current and stay at its peak.
If your capacitors are not 500V WV, you will be over-stressing them.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
