I find that with a 5v4 there is a little voltage overshoot when the B+ comes up. Maybe about 10 to 20%. I actually measured it in my amps, and built extra surge voltage in the power supply.
But, with the Mullard and GE 5AR4 ( I did not measure the Sylvania) the B+ ramp up is over 20 seconds around 30 for the Mullard. So there is no overshoot or voltage surge. I do not know about the currently made 5ar4 and i did not measure any of those. cheers, Dak
