By doing this you've increased the voltage and removed the soft start effectively hitting the tubes with higher HT than designed before they've heated up. This can harm the tubes.
I did the opposite--albeit on a preamp. Added a massive tube regulated power supply to replace diodes!

You know what your doing! I meant in the circuit though rather than in what the tubes can handle.
