It might not be better for the tubesa at all... however, 30% hv has hardly any plate dissipation, but is already sufficient to polarize the power supply caps, and to keep the amp warm. After the hv is switched off for extended period, the power supply section and signal ection cools down completely, and switching back the hv the amp can start warming up from scratch. With 30% hv the amp is always warmed up.Based on the physics of the cathode, 30% is be better than no hv, if the tube is left with that for extended periods. When we switch off the HV completely, the electrode cloud on the surface of the cathode wants to escape (it always wants to escape, when it is heated). If they are not allowed to do so, it will slightly change the structure of the cathode, releasing the built-up internal tension, altering its electron-emission capability.
