ACA MinMax Parts Kit
- Description
- Project Info
- Links
This ACA MinMax parts kit contains all the parts you need to complete the project, other than the ACA chassis and 36V power supply:
- Circuit boards
- Transistors (Toshiba JFETs and IRFP9140/140 MOSFETs)
- Resistors and trim pots
- Capacitors, including two 1F super capacitors
- Jumpers
- LEDs
- Switches, screws, nuts, washers
- One XLR (for mono operation), a pair of RCAs and two pairs of binding posts
- All the wire you need
In order to complete the project you will need to source your own chassis and 36V power supply.
Please note - this is the first batch of this kit. It has been tested and successful kits have been built in the wild. You shouldn't expect any problems, but you shouldn't be surprised if you encounter one either. Your rapid feedback about building this kit is appreciated and will help improve future batches.

Good Day,
I keep coming back to this store to buy up as much as I can! What neat stuff. I’m a complete amateur but this store has forced me to buy a scope and a function generator!!! I have wanted these machines for 30 years. I’m an audiophile enough to know the difference between common and plain to state of the art. For us mortals DIY is truly the only way to achieve this. With a little learning, and help along the way, what a beautiful system one can have real pride in. My immediate project is going to be a dual mono NOS TDA1541A from a tube 6X5 rectifier into a John Broskie high gain aikido using Soviet made 6N16B miniature tube output stage. Just need to learn some clocking techniques and find a suitable I/U conversion ( mono to double the current and geez if I have enough gain I may just use a low value resistor (20 ohms max). It will be built a bit modular so I can tweak things like the resistor as I learn. Once going, I will play it through my VTA SP-14 preamp, my Minmax 10w class “A” amp with my 100db efficiency dual transmission line speakers! All the while I’ll be working on the Aleph J. THANK YOU Neslon and all the gifted folk on the forum. You all are Class A.
