In a simple CRC filter circuit following a rectifier, does the resistor always have to be placed between the 2 positive pins of the electrolytic caps or can it be placed between the 2 negative pins with the same results.
Thanks!

Both ways will work. The same filtered Voltage appears on the last capacitor but you'll need to bring the audio ground point out beyond the resistor.
Thanks Allen.
What I'm doing is using a LM317 for the negative side of a bipolar PS instead of a LM337 while trying to keep things symmetrical on the board.
Also I'm using a transformer with dual secondaries instead of a center tap.
To keep things symmetric, the resistor would need to be in series with the 2 caps' negative leads.

In a CRC the RC is a filter, the first C is a reservoir.
The audio ground should be taken from the last cap whichever side you put the resistor. However, if you get this wrong you will get a lot more hum if the resistor is in the ground side.
