bypass caps across bulk capacitors

[bourdess]

In the course of debugging a hum coming out of one channel of my Aragon 4004 MKII, I found that one of the caps had been leaking onto the floor of the chassis on the channel in question. I've decided to replace all 4 of the bulk (19000 uF) caps and was able to find exact replacements online. It seems that if one is failing, the others may not be far behind. My question is this:

Would it be advantageous to install a couple of bypass capacitors across the terminals of each of the bulk capacitors? Its a very open and roomy design, so adding them would not be a problem.

Thanks,

Mike

It is more effective if you place bypass caps (.2-.47mfd) at the amp PCB. Close to the circuitry.

For an explanation as to why, see section 8 here Linear Power Supply Design

Thanks for the responses. I can see myself referring back to that reference in the future.

Pinch of salt required.
Why do you want to add bypass caps that weren't there before?
