Decided to assemble a second Aleph J. Want to make it a present to a friend. Ordered PCBs and received them extremely fast. As usual, all parts are exceptional quality. Still working on the project, but will finish soon :)
Ultra-fast delivery, excellent parts, no customs issues (as always!). AJ playing again (had blown 2 transistors due to silly handling).Thanks a lot!
Awesome, easy to work with
Bought 2 to setup a small digital streaming system using Klipsch RP 600 M speakers. Have them running bridged mono blocks and they sound so good and far exceeded my expectations, perfectly balanced. Everything in the kit is very high quality and the chassis are very well built.
They push the Klipsch pretty loud.
Im very happy how Its sounds.
Bought the Nutube and PCB/JFETs from the DIYA store, and sourced remaining components from Digikey (the Completion Kit was far and way backordered at the time) - Results were spot on at first power-up, even got lucky with zero Nutube noise - Sounds just wonderful as a front end for my DIY Pass A2.
All worked out well…definitely worth while.
Heavy duty construction with various use configurations. I haven’t used them just yet , but will on the DH 220C project. Thanks again DYI.
Schipping was very fast to Germany!
The First time i ever build an AMP. It works finde witout any rework. I solderd all parts in 2h. From Sound Point of View i can say its amaizing. I use the AMP with my diy Cobra horn BRT speakers. Now i Think i need a sende one. For VOL Control i use a schiit sys. Works great Togeter.
Just finished the kit and am extremely happy with the purchase! It took 2 partial days to complete and the instructions were excellent once I got used to the nomenclature.
The sound is amazing! Dead quiet even with the volume up (and no program material). I am amazed at how accurate the description of different tube types is so obvious.
I started out with a pair of EL-34s, the sound was smooth and clear in the mids and highs, and the bass was very good and tight. I then switched to the high setting of the power mode and put in a pair of Gold Lion KT-88s. Again I am hearing exceptional mids and highs, but the bass now has a “slam” to it that wasn’t there with the EL-34s. I am looking forward to rolling all kind of tubes through this amp as the overall sound quality with each of the tube types just draws you in and leaves you wanting to listen more!
I plan on installing some Russian K40Y coupling capacitors when they arrive and look forward to seeing if they produce any notable difference.
I would highly recommend this amp to anyone who has some experience soldering and is looking for a fantastic amplifier to roll tubes and enjoy fabulous sounding music!
This my second amp. intended to use both of them as mono blocks had some issues getting the new one to work after it was built. (worked fine in stereo mode.) Decided to gift the new amp to my brother as a christmas present. The original is still filling my garage with beautiful music on demand. I had a lot of fun building the amp.
Was very easy to build and sounds very good to me. I installed it inside a diy passive preamp which feeds my diy F6. So now it includes remote volume control and the ability to have it bypassed in case you want to eliminate it to avoid “too much of a good thing” for example, while playing my turntable with it’s tube based phono stage. As it looks, I rarely bypass the Korg because it provides nice sound improvement with all music sources.
This look is not the final, after proving the concept I’ll work on the look
I can’t say I have any experience with different types of solder but this worked great for a first time kit builder. I had never soldered before starting a build on 2 Amp Camp Amps. I built them both in a couple of afternoons and everything worked great on the first try.
This solder was easy to work with along with a Hakko 888.
Highly pleased and recommended.
I decided to build this kit because of the possibility to change the sound with the trimpots. My knowledge of electronics is very limited, so I had some hesitations. However the build guide is very good, the number of parts is limited and the forum is very much alive. I took the gamble and bought the full kit. All the parts arrived in bags, grouped by function. That made it easy to comprehend which was which.
Building was not very difficult with the guide.
It is very nice that various Voltage measure points are described, which gives confidence that your build is ok. Everything worked very nice. I was very happy to see the blue lights.
The trimpots are a bit difficult to adjust because a small movement already gives a lot of change in Voltage (T7, T8).
This is my first tube preamp. I did not know what to expect. I was surprised that combined with my Naim 155 XS it separates all musical elements and gives a very steady stereo image. It gives me more high tones than my previous preamp. I had to get used to that.
I experimented with the the trim pots from 9.5V to 14.5V. Big fun to listen to a large part of my cd collection, to decide what the best sound was. At the moment I leave them at 12V, which as I understand gives the least distortion in second harmonics.
I am very happy with the sound my B1K. Many thanks to Nelson Pass, the writers of the build guide and the diyaudio community.
After taking a 20 year hiatus from DIY electronics, I thought this project would be a good entry point back. I was not wrong. It took me a weekend to complete, double and triple checking (oops, 100 ohms don't go there). I was pleased with the process and the excellent directions; pictures help so much. Turned it on and adjusted the DC balance, and no smoke! It works! I have it setup as a near-field desktop system, streaming mostly. The clarity and spaciousness of the sound field is what has wowed me so far. Next up is the GR Research Desktop Mini speakers, almost complete, can't wait to see how it sounds with them.
