Power amp rectifiers

[d3imlay]

What is the preferred alternative to the standard 25 amp bridge? My application is for a 200 watt amp. I can use either discrete devices or a full wave bridge.

Hi,

If that's a mono 200W/4ohm-RMS amplifier, then let's use a 15A/200V bridge. For stereo 25A/200V.
If it's a 8ohm amp, then use 10A/400V for mono, or 15A/400V for stereo.

Regards,

Fast recovery? Schotky?

A 35Amp 400v would be my selection $3.85 thru AlliedElectronics

Unless you can hear the differences,otherwise a 35A bridge will do the job rather than using the fast recovery or schottky.

Thats the bridged rect. I used in both of my ESP P101's🙂

Nor fast recovery, nor schottky. Use "normal" bridges.

Hi,
I have started using RC snubbers across each of the four diodes in a standard 25A bridge in power amps upto 300W into 4r.

I have always used caps from line to return on the primary, the secondary and the DC side of the PSU.

They seem to be quiet.
