Hybrid rectification tube/diode

gmant123 · 4th January 2013, 08:35 PM

Hi All and happy new year!!!

I want a make a 300b power amp, with hybrid rectification, tube/diode, but on hand only have HER508 diodes, they can work??
The tube rectifier is a 5Z3.

Diode Datasheet

Example of rectification..

Thanks for help..

Alberto.

You didn't indicate the sec.voltage of the transformer ??
The max reverse voltage of the diodes hase to exeed (largely) the Vp of the transfo.
Ater the rec.tube the capacitor is limited to 32µF not 100 !

Hi, thank you for reply.

Is a choke load PSU, transformer secundary 510V.
Trafo-hybrid rectification-10H choque-45uf film-5H-45uf film, one 5H per channel.

Regards.

Alberto.

It seems HER508 diodes are OK.
