The power supply filter config is CLCRC or LCRC.

Where's the best place to put a bleeder resistor?

First, is a bleeder resistor truly necessary? I mean, if this is a low voltage, low-energy supply, a bleeder resistor isn't going to do much but bring the overall efficiency down. Where they are needed is across each capacitor in a series stack - i.e., to equalize the leakage currents of each capacitor in a high voltage supply - or when more than a couple of joules of energy are being stored (joules = CV^2) because you are getting into screwdriver-vaporizing territory.

As far as where do you put them, well, across the rail. If it is a dual-polarity supply, then from each rail to ground. Simple as that. I suppose some argument could be made about putting them across each capacitor - especially if high voltage and capacitance are involved, but unless you need to drop more than a watt across the bleeder, it would be hard to justify.

A bleeder is only necessary if you have

1 circuits that needs to be really reset like micro controllers or if you are have

2 trouble with bumps and simliar at startup or

3 use high volatees like tube amps.

Calculate the resistor for 30-90 sec discharge time. 4.7-22 kohms or something like this.

You can place the resistor anywhere before the regulator.

If it's a battery application => Skip the bleeder!
