Universal Power Supply

I used this for an external dual mono PSU setup for two Amp Camp monoblocks - great board with plenty of versatility. I snapped off (very carefully) the diode section as I opted for bolt down bridges. The support thread was very helpful too, I had a few questions that I needed to confirm and the community was very helpful and fast.

I used two of them to build two Honey Badger power amps in mono configuration. It works really well and the the documentation is clear and detailled. I have no complaints whatsoever.

Built 2 of these boards for a pair of Honey Badger amps. Excellent boards, quick and easy to build. Work great.

As usual the PCBs are beautiful. Wanting to make a FirstWatt amp, I found this kit too "universal". I had to figure out what was necessary and split the diodes part of the PCB. It took me a long while to manage that, slowly and cautiously with a cutter but the result is up to expectation.

I have built several power supplies using the Universal Power Supply board from DIY Audio, the end result has always been the same, rock solid power and exceptionally quiet. I have used as a single power supply and dual mono, both worked flawlessly. I highly recommend especially if new to the hobby. The large amount of documentation is very helpful.

Arrived within a week to the UK. I’ve used the boards many times, excellent product. I used the diode boards, instead of separate bridge rectifiers this time. It maybe my imagination but the sound output appeared smoother.

I used the board in an Aleph J build. It's wonderfully quiet. The board has many build options and takes a little reading to decide how you want to use it. The diyaudio discussion thread was very helpful. Highly recommend.

Very good board. I bought twice

Heavy duty construction with various use configurations. I haven’t used them just yet , but will on the DH 220C project. Thanks again DYI.

This power supply is easy to build and it works very well.
My builds have been silent when connected to Pass amplifiers.
Very easy to adapt to whatever is required in your build and plenty of support from the DIY forums.

The P.S. boards would be a bargain at twice the price.
Board quality is outstanding. .And diyAudio staff are patient, and helpful. ( I had to order twice, because the first time I kept making errors entering my own address!. Staff helped me get past these errors, and on to a new order.). Boards arrived very quickly, and in perfect shape because of the care taken in packaging.

This board worked well. It made the job of assembling a solid power supply a no brainer. Broke off the rectifier section and used monolithic bridges..

I have built three of these into 2U Modushop Galaxy 240mm wide chassis and used them as seperate PSUs with a range of Pass diyAudio amps....F5, BA3 balanced monoblocks, F6 balanced monoblocks, and M2X built into matching 240mm wide x 300mm deep chassis. They always work very well. The Build guide is excellent ( thanks 6L6 ) but could do with some additions. Specifically the mains input junction strip construction can only be found in the older PSU build guide produced by another writer, and the components for this ( thermistors etc ) are not included on the BOM

Sturdy, well designed, thick traces and good usable options.

Nice board. The option of breaking off the rectifier section is good. A little bit larger holes on the dc output side would be nice. Thank you, Bill

I have purchased quite a few boards, kits, and chassis, always great service and quality items!!

Great stuff! I highly recommend you to buy some.

Es la tercera vez que pido estás PCB para mis proyectos. Pese a que hay quien prefiere montar algo más específico dependiendo del proyecto a realizar, a mí me ha dado muy buen resultado en todos los que he realizado, además creo que la "universalidad" de estas PCB es otro punto a su favor, ya que se pueden adaptar a muchos proyectos diferentes.
Excelente calidad.
Gracias de nuevo.

Parfait, rien à redire
Je vais commander 3 autres cartes.
Encore merci pour la qualité et la rapidité de votre magasin

Built 2 of these boards for F6 & F7.

Excellent Boards, great use for tube power supply as well as Solid State, good for spreading resistor loads across many resistors, you can use a lot of different diode arrays on rectifier section, which also has provision for snubber network, or just not use that board at all, I'm using just 2 x730uf Rifa Caps on one side of the board for CRC supply, you don't have to populate the board completely I would definitely use them again for other builds, superb quality with wide thick tracks!

It was received in a flash and as said simplified my Pearl 2 ps build. Very practical to implement.

The price and quality are excellent.

The UNIVERSAL POWER SUPPLY PCB's or very nice quality boards. I would recommend that the ground be isolated on each half of the PCB so two independent +/- supplies can be created for power multiple analog circuits. If you look at the PASS DIY 40 watt amp and split the ground so each 1/2 of the filters and supply 2 independent voltages. To support a Transformer with two secondary and each secondary having a center tap. I do like all the options the board presents, thumbs up.

Some rather large grounds require a lot of heat. I used Sn63/Pb37 at 780 degrees F. Careful with screw length and orientation if you're using a TO-220 diode and heat sink.

Dear all, I bought this pcb to build a power supply for the phono preamp "Pearl 2": maybe it's exagerate, but I think it's the best power board I saw. Some components are still missing, but in a few weeks I'll make it work.
The pcb is really exellent designed and done.
Thank you, let's talk soon. Take care

These are wonderfully configured and constructed PCB's for assembling "pi" style C-R-C power supplies. They include solder pads and circuit traces for inserting diodes, but can also be used with monolithic full-bridge rectifiers, like the excellent IXYS FRED-based fast recovery types I like. They also include solder pads for block terminals to make quick connect hook-ups easy and safe and LED voltage indicators to make trouble-shooting less trouble-some. Very highly recommended for your next amplifier project with either single-ended or bi-polar power supplies.

Received board

Great looking board,very well made top quality.

Very good choice for Audio
