Do the Selenium rectifiers acts the same as silicon rectifiers?

[ln76d]

I have never before used selenium rectifiers and my knowledge about them is really poor.
With silicon  rectifiers we can use much higher than are provided - for example for rectifiing 24V a 600V rectifier is ok - is it the same with selenium rectifiers?
My intuition tells me - yes - but always better to be sure
For example i need E150/50 rectifier which probably is 150V/50mA, can i use E350/30 (350V/30mA) instead?

Why use selenium if you can get modern silicon rectifier?

Because they smell more intense when overloaded ?  :

Hi,
If your intention is to use it for the rectifier in AKG N12K power supply (HV part), the answer is yes, IMO.
Anyway, be careful with seleniums.

Hi Milan,

yes exactly I know that selenium rectifiers are unstable and capricious, that's why i wanted to be sure. Thanks!

I knew that this would be first question in this topic
As above. I want to make AKG N12 power supply clone. Why?
I have most of the parts, including selenium bridge b25/20, resitors, capacitors so why not?
I'm curious would this affect to the sound.
Without PCB it's simple construction.

Yes, i'm addicted i like to sniff the smoke
