diyAudio Store

Tightly matched quartet. My ACP+ sounds wonderful with these.

Fast & safe delivery even to Prague!

Recibí el pedido relativamente rápido (España).
La calidad de la PCB es excelente.
Aún no he tenido tiempo de montarlo, pero publicaré unas fotos tan pronto lo haga.
Está diseñado de forma que varias partes de la circuitería se puedan modificar de forma sencilla si surge algún tipo de problema como oscilaciones o ruido, además de la posibilidad de montar diferentes medidas de componentes.

Muy contento y con ganas de empezar los proyectos (también estoy a la espera de algunos componentes para montar en unas PCB de F5 que recibí de diyaudio hace algunas semanas)

I've even dug old boards and components up out of the basement and completed the assembly just for fun! Wouldn't have done that in the past.

I have brought the JFET for my F6 build. I have also brought the ACA kits, F6 PCB, MOSFET, UPS, chassis and many other parts for DIY Audio store. Every products came with high quality and fast shipping. Every question from me was always promptly responded within a day. Can't find better service than this! This is the default place to go to for my DIY audio hobby!

Great product.
It does what you expect.

The DiyAudio Store does a very good job and serves our community extremely well by providing JFETs for the critical parts of many audiophile quality diy projects. I intend to use this purchase of a matched quartet for a F4 clone.

Looks excellent. I did not build the project yet

Excellent very helpful staff when I stuff up order

Nice flow into the wire, sets almost instantly.

Fine PCBs. Thank You.

I originally bought jfets from eBay, matched them well but couldn’t get my DCB1 to work. Bought a matched quad from DIYA store- problem solved!

I have 4 of these. Enough said!

Perfect. Will buy again!

Why play roulette with "SK170" devices that may or may not be even close to what they're supposed to be?

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

I managed to ruin some traces on an M2 build. As I was researching as to if I could resurrect the build, when I happened upon the M2x thread, and jumped at the chance. The boards are wonderful of course, and they promptly arrived. I built a pair of mono-block amplifiers with boutique parts, and a set of Fairchild FQA mosfets. I have completed the Mountain View and Ishikawa boards so far, the the other 3 are in process.

These amps sing, and easily are the best I have built. Highly recommended.

As the title

1st class as usual. Always among the very best in communication and follow through.

Hi.
I have received everything well and it looks very good quality.
I have already mounted all the components on the PSU board and the rest as well, but have not been able to test it yet.
I have another order for an F5 kit pending and I think some other item, but I imagine it will be stopped at customs.
I am eager to receive it and be able to finish the project. Surely this will be the first of several (looking at the quality of the material, I am already waiting for there to be stocks for an aleph J).
I hope that at least it brings back memories of an pass labs aleph 0s that I had years ago and that I will always regret selling.
Many thanks to diyaudio and first Watt for giving us the opportunity to enjoy these projects.

This is a preamp for us DIYers offered from the mastermind of the PassLabs preamps - Wayne Colburn.
It sounds very detailed combined with a clarity and without harshness. Bass is solid and controlled. I used
TOSHIBA TTA/TTC004B for the outputstage. Drives all my Poweramps (F-5T, BA-3, BA-1, M2X, 50W-SE-Schade)with ease.
Absolutely no noise audible in my combinations. Can also drive headphones (with big BJTs in the outputstage).
PCB is of excellent quality and was delivered very fast. Thanks to the DIYAUDIOSTORE-team!
Build it - enjoy it!

very happy with them. Nice to have a reliable supplier. I just wish they had more stuff available.

While I'm still doing work on the pre-amp design, they are quite well matched. I'll be back for more!

I wanted a high-quality HPA and didn’t wish to pay over-the-odds for sub-par consumer designs. As it was designed by a pro from a proper hi-fi company, I saw it as a bit of a no-brainer decision. The build took me about six days to complete with cutting chassis etc and making a few mistakes along the way. As it was my first time I wanted everything to be correct and my fussiness paid off this time - On Power up all was perfect and I was pleasantly surprised. Would definitely recommend this build to those who appreciate real hifi and music-lovers who don’t want to break the bank. I am a music-lover not an Audiophool.

As always, a great product from the Store.

Fast delivery. Excelent quality. Me :)

I've gone through half a pound of Cardas solder so far in the pursuit of DIY learning....The Cardas is very good—but FireMetall is BETTER. The diameter is PERFECT, flow is awesome, flux is very consistent. Well done DIY Audio!!!

Everything you need for finishing the back panel of a HiFi2000 amplifier chassis. All first class stuff. I especially like the integrated IEC power connector / fuse holder.

Easy and fun build. Very well documented and the the panel PCBs are seriously ingenious. At least for me, the case work is usually the biggest struggle... PCB is great quality as usual and the price very fair (admittedly I ordered during the last Black Friday sale).

So, how does it sound? With the HD600 the stock Noir sounds better to my ears than my heavily modded BH Crack w/ Speedball (Mullard and Russian tubes, fancy output caps, Alps pot, Triad choke etc.). For some reason the Noir manages to reveal a lot of details, whilst being a very comfortable listen. "Natural" comes to mind. The biggest surprise was however when I tried it as a preamp with my F5. The Noir somehow gets rid of the slight harshness of the F5, while being very detailed at the same time. Same as with the headphones, the combo sounds very natural to me. The base has a lot more texture than my tube preamp. Obviously, it's not an ideal preamp with just 1 input and it has too much gain for my system, but somehow I can't stop listening to it.... In fact, I'm listening to that combo while writing this.

Beginner or experienced DIYer, everyone should give this simple and elegant design a go.

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.

I wanted another Balanced input/output preamp, as my BZLS is from a 1990's design. So I bought two boards which are now populated, SMD JFET's a breeze to solder. I like the fact that Wayne specified JFET's and components easy to find and purchase for this project.

Shipped incredibly fast. quality of finish is excellent. Only problem is that the top and bottoms are held on with tapered head screws. Tapered screws are meant to be countersunk. because it is not the head does not seat properly and sticks up slightly. I will be replacing with a button head design that will stick up still but look correct. Minor quibble.

Good stuff Good people.

been looking for a linestage that fits my M25 (Babelfish) better than BA3FE or other chippy preamps i tried.
this is it! clear sound - not mumpfy, not sharp.
till now i've just made the standard model running on 20VDC. no bigger semis in Q8/10 position.
still looking for a nice housing.
Thank you Wayne!

High quality board as usual!!! Very nice project!!!
