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.
What are you guys using to connect all the grounds to a single point?
Soldering or some kind of post?

I use solid core copper jumper between ground traces.

An interesting implementation of the regulated PS option can be found here: wavelengthbrickpowersupply - mpbarneysources

I bought your Aleph J psu boards and PCB and have a question for you. Pass uses 120,000uf worth of caps in his psu, but you only have space for 2 possibly 4. what is the reasoning behind this? what caps would you suggest for quality implementation for the Aleph J.

What is the reasoning? To use not more parts than necessary.

Attached is search result for compatible caps from digikey which are in line with what Pass uses (they are also rated more generously)

I used the universal power supply as a regulated +-15 supply using LM317 and it's compliment. To get the voltage to +-15v, I used a adjustible resistor. One of the legs on the pot is floating or not connected. I know it would be best to remove it, measure it and replace it with a resistor, but I would like to keep it in for now.

What should I do with the third leg of the pot that's floating? Leave it floating, ground it or attach it to the center pin of the pot itself?

Thanks,

Vince

My Poseidon's Voice Katalyst PS uses Peter's board as well as a Paul Hynes' shunt regulator and has worked flawlessly for years.

Best,
Anand.
