SMPS DC Filter P089ZB Kit

Just what I needed. It eliminated all hum and hiss from NuTube harmonic generator board so I could use standard wall wart for 12VDC power. Its small size allowed it to be mounted in a wooden cigar box that I mounted the NuTube in.
DIY store was great to work with when the USPS lost it in the mail the first try.

Thanks to the excellent filter my FE2022 build is exceptionally quiet, which enhances its ability to capture fine details, N + THD < -90dB with 48V SMPS.
Many thanks to Mark and diyStore.

Beautiful little kit. The sound of the B1 Korg is more detailed.

Sounds great with NuTube preamp and Purifi Eval1.

I've built and implemented a couple of these now and they are excellent. I'm a big fan.

& it works great.

Kind of funny that I missed that part, but the packaging was great parts are sealed and on time.

Was surprised how well this works, bought several, used one on my 6-24 crossover. To my ears, bass has more authority and image is more vivid . Will try the other on the Korg B1. Going to get 2 more for new projects. Highly recommended

Easy to assemble, all the necessary parts are included.
With my Meanwell LRS-75-24 SMPS I noticed a significant improvement in ripple and noise.

Wow, talk about an easy upgrade. Took about 15 minutes to solder together and about 20 minutes to drill 2 holes and implement into the B1 Korg kit chassis. I used taller standoffs so the boards were at different levels. Otherwise it would be a very tight fit.

My B1 build is pretty simple. Standard kit but with Vishay Dale resistors, .22uf wimas as input DC blocking caps. 10uf silmics in the middle and 6.8uf clarity caps on the output caps. Whatever I had in my box. Makes for a beautiful sounding preamp.

For the clean side of the Allo Digione Signature....... the filter works like a charme

Well done !

A great device works great and handy having all components in kit

Having recently built a ACP + and decided to use a Meanwell internal 3amp SMPS. I already have a lot gear using linear supplies, as I have been wary of using SMPS supplies in the past and putting out 'gunge' into the supply. However, I am thinking things have improved in their design and a lot of audio manufactures seem to be using them now as well. And as I like leaving stuff on, I thought why not try and save a few dollars on the electricity bill. This filter is very well priced and easy to implement. Not sure how much difference it makes but the ACP+ sounds very good to me.

Easy to build...and works great!

Beautiful little kit, have only tested it with my Starving Student HPA and it definitely adds transparency to the sound. This kit is highly recommended!!!

Easy to assemble. All parts needed are included. At this price it would make a good kit to practice soldering.

Hello, This is a great little filter project at a great price. Not much else that can be said, works as advertised.

Gave a couple of these to a microwave engineer for a very cheap power supply he had hoped to use but was too noisy. It reduced the noise by more than 100 to 1, and made the PS usable!

Quality parts, easy to build, definitely improving power supply on each small voltage unit.
