Universal Power Supply PCB

[vdi_nenna]

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

How do I get a hold of the PCB's for this power supply?

Contact me through forum mail.

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.

 

[Peter Daniel]

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

Either attach it to center pin of the pot or replace the pot with resistor.

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,

Peter,

I'm thinkning of using an MUR3020, MSRF860 or MUR1520 with your rectifier boards for a balanced F5. What heatsinking do you use with these pieces?

Peter,

for R2/R4, is there a formula to calculate the value needed for a certain output voltage?

thanks

Which regulator you have in mind?

Need a power supply board

Peter,

Need a power supply board for Pass F5 build. Let me know where to order and how to order.

Thanks

Hi Peter.

I wish to use my universal PCB I purchased a while back from you to provide 24V for a Pass Labs B1 buffer.

R1 = 240R
R2 = 5R adjustable

I'm using Black Gate Standard 1000uF/50V for the main PSU caps either side of the LM317 on your board.

Do I need to bother with C1/C2/C5 in your opinion?

Many thanks!

- John

 

[Peter Daniel]

I wouldn't bother with bypasses on main caps but would probably install 10uF cap across adjustable resistor.

Great - I'll do that! Thanks Peter much appreciated 😀

 

[johnm]

P.S. Sorry knew there was something else! Peter do you prefer using a CT transformer and a pair of diodes with your PSU board, or a non CT transformer and 4 rectifying diodes? Which is meant to be the best? Thanks

ps boards

are these pc boards still available?
where can they be purchased?
thanks,

I just run out of therm few days ago. Might get more in a future though.
