You could from the last cap (break from the OP tube) install a series connected damper diode, heater of such diode would be switched appropriately (relay) and therefore retain the slow enough B voltage ramp up courtesy of the tube rectifier (assume). Good stuff to be thinking about (better than the proposed circuit by a million miles)\\\Shane.
