What is the optimal grounding scheme for this PSU when used as V+/V- ? It is for an F5 amp.

Specificaly where is the best place to pick up the chassis ground? Best place to hook up the neg speaker terminals? Do the two center "ground" traces need to be jumpered together?

Thanks!
carl

Yes, it's recommended to connect center ground traces (red jumper in attached pic). That would be your power star ground where all other grounds are connected (also the chassis ground). Attached is also wiring diagram for F5 amp.

Thanks Peter,

I essentially connected as you suggest with the exception of not using the jumper on the PSU board. I ran 6 independent ground leads from the GND of the PSU - one to each neg speaker terminal, one to each amp board, and two to the chassis(one from each side).

Everything appears to be functioning normally and the amp is quiet.

What kind of parts did you use in the regulator? I can only see the Nichicon (what value?) and the LT part...

Just follow the datasheet: http://www.linear.com/pc/downloadDoc...55,P1358,D1722

The large caps in a pic are 4,700uF

I may have made an error here, you say isolation pads are needed? Nuts I used transistor grease and put them directly to the case. I guess I need to remove the grease and use isolation pads here then? I havent fire it up yet thank goodness!

Depends on the rectifiers you use. The ones I use FOR MY F5 HERE do not need to be isolated.

I did not deploy the use of Peter's rectifier boards though. The Vishay rectifiers are cheaper and a little easier to use.

I uised the MUR 3060 and Peters boards

A-ha - yes you will need silpads or something. I started down that path and thought I would try the vishay units out to save some $$$ and they work fine.

Peter, How would I utilize your power supply boards for the Pass Pearl 2 that I am building.
