Damper diodes as rectifiers
It's quite normal with silicon rectifiers for the peak current to be ~ 10 times
the average. I expect the voltage drop of thermionic diodes reduces that ratio
but I dare say these diodes weren't intended to pass such high peaks.
Looking at various data sheets, it looks like a tube can handle only
about 5 times its average. It's something one needs to pay attention to.
