Have you try to compare a normal 35A bridge rectifier with 4 schottkys???

Predator864 · 22nd May 2008, 04:25 AM

Well, I dont how the Schottkys will operate in my amplifier.
I was thinking of something better, like 4 MUR3020 with snubbers.

I`m thinking now about those ceramic caps. To put or not to put some Evox Rifa polypropylene caps.

I just bought 5 SDT12S60 Rectifiers.

The price was very good: 14 Euros ship. incl. to Romania.
