Best practices with tube rectifiers

[Alan0354]

That's what I have in my two build. I use SS from the get go, forget the tube rectifier and use a sag resistor. I did ask this question and people here say they can hardly tell the difference.

I suppose the idea was to let the rectifier warm up before applying the voltage? Is there any advantage in letting the rectifier warm up? Like for power tubes where it will increase tube life.

I don't think this has been addressed. This does not extend power tube life, and may shorten it (if left in "standby" for long periods of time).

Letting the rectifier tube warm up and then asking it to deliver current suddenly "hot switching" can cause the rectifier to pop. Merlin covers this here: The Valve Wizard
