As a home hobby student to electronics I need a question answered please
so I can be sure ahead of time. The enclosed crude jpeg is the question.
Is this the proper way to central point ground a positive & ground power supply.
I got the origional off the ESP web site but am unsure when working with
this type as to not blow up the capacitor. The origional power supply consited of positive and negative rails and also a circuit common rail. This power supply is for a audio project to reduce hum and eliminate ground loops in a metal enclosure.

 

The cap would be fine in either method. What you are doing is connecting the power line safety ground to your amp's metal box. *IF* everything is your system is connected to the same point on the AC safety ground then there is no problem. If you plug things into several outlets then, well...

I have the feeling the true audio guru's here will scream if you do that, IMHO you're more likely to bring noise into your amp this way then to exclude it.

 

Would two additional 100NF @ 100VDC Metal film capacitors help out with noise.
What I need is this power supply with a 24VAC @ 4 Amp transformer and 4700UF
Or 6800UF caps to power two matching amplifier boards. They are rated at 36VDC at 2 amp each board. Am I right to figure that the voltage will not drop if the amperage is present.
