bypass caps with hexfred bridge rectifier, etc.

Tweakers' Asylum

Tweaks for systems, rooms and Do It Yourself (DIY) help. FAQ.

I installed a full-wave bridge rectifier, using 4 discrete hexfreds, in the output supply for my amplifiers. The bridge sits across the plus and minus windings of the power transformer secondary. The supply is floating wrt ground. I have several questions related to this application:
(1) Is it a good idea to bypass each hexfred with for example a .01uF cap?
(2) I have seen mention of the use of resistors between the transformer secondary and hexfred-type rectifiers. Is this applicable to my set-up, and if so how do I calculate the correct resistor value.
(3) In discussions related to the use of Schottky diodes, many have recommended installing a snubber RC network, I think across the transformer secondary. Is such a network of any value with hexfred rectification?
Thanks for anyone's input.

but Hexfreds DO generate some noise.... - Lew 07:21:01 06/11/02 (0)
