Please note: Our Italian chassis partners Hifi2000 are closed for summer holidays between the 3rd to the 25th of August 2019. Chassis shipping will resume during the last week of of August, most likely towards the end of that week. We do apologize for any inconvenience this causes.
Thanks to all the good folks on DIY forum for providing easy to follow guide and suggestions/tips. I built my Whammy in 4 days (2-3 hours per day). The most difficult part was the chassis as it's my first real diy project and I didn't know how to properly use power tools :) Quality of the board is great and the shipping took only one week to Ontario Canada. I'll definitely consider more projects from the DIY audio store! Thanks for making diy accessible to newbies!
The boards are of excellent quality. I must also commend the speed of delivery by DHL to France. I am going to enjoy building this amp.
Tuve la suerte de que me la contruyo mi amigo Javier que es un reputado tecnico y tengo que decir que, ojo, sustituyendo la fuente de alimentacion conmutada por una fuente de alimentación lineal, un cable de altavoz de 16mm² de OFC y con unos altavoces muy sensibles y buenos graves como Klipsch R-24F, el sonido tiene poco o nada que envidiarle a Meridian 205 Mono con Dynaudio Audience 62. Y eso es muchisimo decir para cualquiera que conozca Dynaudio amplificado por Meridian. Ditto.
Build completed without issues thanks to the excellent build guide by 6L6 and extended notes and tips from Pete Millett. The kit arrived intact and in excellent shape. Thank you to Jason for his patience and guidance whenever called upon for assistance. The build was not difficult when approached with a reasonable amount of patience. Finished amp looks amazing thanks to the precision and sheer quality of the supplied enclosure. A golden nugget of a HP amp with pre-amp capability thrown in. Listening experience has been amazing. Immensely enjoyable and rewarding build. Highly recommended.
I ordered the Elekit TU-8200DX after researching it extensively on the DiyAudio Forum. The kit arrived as promised. Emailed questions were answered promptly. The amplifier is very nice. I substituted a few components as suggested on the forum with outstanding results however it sounds great as shipped. The TU-8200 driving MarkAudio 12P/Super Pensil speakers with a Raspberry PI4 and HifiBerry DAC+ Pro and streaming Qobus with great results. There is more than enough power and the bass is impressive.
These electrical insulators/heat conductors are excellent ant easy to work with. NO MORE PASTE! Nice.
I really enjoyed building this amp. It took me a little longer than I thought but I was being very thorough and carefull. It was prity straight forward as it was my 1st attempt at such a project. The walk through build guide was invaluable. The case was nicely built and the whole thing looks great and sounds excellent. Iam using klipsch rp 600m and works great with these.
The only small point would be the front switch is a bit sensitive it sometimes doesn't turn it on so I turn it off and on at the power point.
Great little case to match the ones supplied with the full ACA kit. I ordered the no holes on front cover option, which took a little thinking about since the included instructions are for a drilled cover only but it went together very well once I'd worked which screws to use in the blind holes on the front. Super fast FEDEX delivery from Italy to New Zealand. I'll be ordering more for Phono amp and power supplies before long.
Arrived in perfect condition with all parts. Went together without any difficulty. Makes the aca itself look properly made and permanent in a home.
Great board. Well made.
sourced chassis, Nutube, Board and FETS from DIYAudiostore
used Dale resistors, Nichicon KZ and Elna caps, Alp pot,, the sound, no cursing but its you know great. very great looking and pro with the chassis and can't believe the size. Does ring on input change but stops. Much Improved when hot glued Nutube to board. Value/price can't be beat. Using with DIYAudio F5 also built this year. Loving both. Much gratitude guys and thank God for NP
For college Electronics final project
Combined with my Duel mono ACAs In my hand built backloaded pause text BK 20 speakers I definitely will pass electronics analog class. Instructor is an audiophile amplifier nerd 👍. Next semester‘s class tackle the Alpha J Mono Blocks.
Being an amateur and a student in electronics college instead of picking a ready built simple cheap Chinese made power regulator I opted to buy the Super Regulator. it definitely has made me learn more how it works in which each individual component does. Excellent learning tool. I’m still learning
I purchased the B1 with Korg NuTube PCB and triode last year and waited patiently for the chassis kit to be released. Surprisingly, Jason and Jim also released a Completion Kit, which eliminated my need to acquire the caps, resistors, and diode to complete the PCB. I’m glad I waited as this kit was easy to assemble with Jim’s (6L6) photos and advice. I still have to work to reduce/eliminate the NuTube microphony that flares up occasionally, but this is a special line stage preamp with incredible detail, separation, a large and deep soundstage with excellent imaging, and organic tonality. This is a bargain and will best many vacuum tube line stage amp kits currently on the market at a lower cost.
This project was my first amp kit. It went really well. All parts were there and working. Online instructions were easy to follow with ample photos and explanation. Just need some tools aside from the kit. Everything came pretty quickly, even the case from Italy. The amp actually works, and sounds good!
Arrived in good condition works perfectly no problem.
Good quality and excellent help on the forum.
This is a super nice reg. I built one for nuhybrid amp and hiss level is greatly reduced! Overall it is very easy to calculate resistor values, the ground resistor R7/14 shares the same voltage as your choice of V-ref. Nice product!
Wonderful and easy to build amp kit. Great build videos and easy to understand builds instructions. Parts quality is very high...and the sound? Well, the sound is amazing. It drove my Tekton Double Impact with ease. My only wish would be to have a higher 4 ohm output rating. Highly recommended.
Kit is well put together and has everything needed. It has a pleasant and characterful sound. Enjoying it through an ACA and some Q Acoustics speakers. Very good for the price.
Shipping was fast and tracking notifications were helpful. Thanks DiyAudio for all of your hard work.
Received quickly and now ready for winter darkness with DiY soldering for new audio Project.
Nice quality of the PCBs
I ordered these replacement JFETS to replace a couple in my Amp Camp 1.6. I had an unfortunate power surge while I was
experimenting with a power supply, and my JFETS took a 50+ power surge. They appeared to survive, but since their MAX
rating was 40 volts, I wondered if their demise was in the cards, so I replaced the originals with a couple of the replacements.
All is well, and I now have the comfort of mind that my Amp Camp Amp will be singing and well for a long time! GREAT AMP
by the way, for any that have not heard of it. Well worth the acquisition.
Thanks DIY Store for GREAT service, simply among the best outfits available to us DIY-ers :)
Very good layout and performance.
Just finished M2x and mountainview buffer boards. Very organic and musical amp. I like it a lot. Highly Recommended.
The amp camp amp works really well, as in quality sound comes out, including clear clean-edged deep bass. All the parts were there, everything fitted, and it wasn't hard to build them. There is an "I made this at home" fart noise that happens when powering an ACA up. When using two amps (as monoblocks), one for each speaker, that noise is missing (a nice change). A single amp sounds excellent, but comfortable volume only. Two amps and there is more volume, but if I turn the CD player headphone out volume all the way up, the sound coming out of the speakers is definitely less impressive (crowded in the mid range and lacking clarity over all). Also, since the headphone jack is not intended to be a line out, there may be an issue with frequencies ie bass mid range and treble, having a drier balance. So I am waiting for a DIYaudio preamp to arrive - I could do with a tiny bit more volume sometimes, if available, and a proper preamp is the next step for me sound wise too.
Last thoughts - if you live on solar power, you will be surprised at just how much power goes in, and keeps going in, to a tiny class A amplifier, for not a lot of noise out. But there is no doubt quality sound happens. If you already have expensive amplifiers, then listening to heavily produced music mightn't show much difference, but simple CDs like Joni Mitchell's Blue album, in particular the single voice and guitar tracks, reveals tonal shifts and nuances in the voice that definitely surprised me. Speaker lead choice makes a difference. RCA lead choice makes a difference. You can buy good plugs and experiment making your own.
Thankyou DIYaudio people, thankyou everyone. I am very grateful for the joy these little amp camp amps are giving me.
Very good chassis, good price, it houses my m2x amp.
Favorite features: predrilled base plate, predrilled heatsinks, looks great (black version), saves 100€ on build cost
I first bought an F5 kit from DIY audio store. It was an awesome sounding amplifier but I felt it had too much gain for my system (I have very sensitive speakers). I then got the F4 amplifier PCBs, that I could use in the same chassis I used for the F5 (I had to augment the PSU with another board for more capacitance). The F4 is perfect for my system, I don't have to listen at very low volume setting anymore butt I still do have plenty of room to increase volume if needed. The sound is great. The F5 has exceptionally fast transients and a somewhat lean sound with tons of details. The F4 has a more relaxed presentation, not as fast as the F5, but I felt the sound has very wide soundstage, and the details are still there. Very enjoyable to listen to. Overall I am very happy with this amp, that I know will remain in my system for a long time. I am very pleased with the service from DIY Audio Store, and the quality of the PCBs and parts they provide. Thank you!
DIY Audio’s performance leaves big corporates for dead.
From prompt excellent customer service, through an extremely well thought out high quality project to the associated, well managed forums, my experience has been the very best.
My project almost fell together. I’ve reached the (no)smoke test which has to wait ‘till I’m back from holiday.
Recommended for anybody who can follow straight forward instructions.
Thank you :-)
Really top grade PCBs, the Mosfet seems far enough for heat spreading well , I love it.
Beautiful PCBs, all received as mentioned, an excellent kit, but it always the case with the DIY store.
I wish the LED and its resistor were include but no big deal.
For the Jfet , it seems more complicated as they must be paired.
But "in fine", the kit is a big time saver and well done !
I am very happy fast shipping well pack and vey good pcb quality very satisfy looking forward to built it
One thing that I didn't realize is on my Macbook the BOM link auto downloads an Excel file without a notification. I missed the download at first.
Really like the high quality DIYAUDIO boards.
This amp sounds terrific, looks great, and was easy to build. Can't recommend it enough, AND customer service was SUPERB.
