Threshold 400a bridge rectifier.

Re: 400a outputs

2 Use IXYS fast recovery rectifier

Jon of VintageAmp

Are there any fast recovery bridges and if they are which one you would advise for replacement for typical 400 - 600V 35A bridge?
Thank you

AR2,

This link is the results of a post search for IXYS starting from the first mention on the forum back in '02. There were many such discussions on the all aspects of using and obtaining and making high speed bridges.

even if I doubt that you'll hear difference

btw:

there are few catches.........(22?):

Thank you guys, it was more curiosity since VintageAmps posted his opinion on modding in another tread, when Netlist decided to move my question in a new tread. I normally use fast diodes in my rectifiers, but I was curious what he was recomennding as there are not too many high powered fast recovery bridges.
Thank you for the links, I will check them out.

If I recall well, Mr. Pass was sceptical about any benefit of having these rectifiers in a audio circuit, but he changed his mind and he is using them in his latest designs. One fact is for sure, they are not going to turn bad amp into good one, but when you have a good design any change in parts such as rectifiers, caps and sometimes resistors could bring subtle improvement. Same stands for cap bypassing, having dual bridge rectifier, and similar. Power supply will work in its simplest form, but with the above mentioned we could cirtainly improve some.

😕
but I assume that you'll use it for reviving chopped guts of old treshold.............and that's crappy amp

I know that you know........sala mala

btw.....I just forwarded one mail,for your eyes only
