That’ll look nice! I may have to do something like that. I thought about doing a batch of blank PCBs (kinda like the ACP+ ground plane) for attaching feet, but your idea is simpler and will look better
Codyt, any possibility you might make some single chanel boards ? I asked earlier if this amp would work with laterals and Nelson said go for it so I was thinking of building this amp in a gutted Halfler DH220 case. I figure having a negative temperature coeficent I wouldn't even need the source reistors if I used laterals.
The old DH-220 case is a perfect size for this amp. If you have a set of the Hafler matched lateral Mosfets, you can leave them installed in the heatsink flanges. (Clean and apply fresh thermal grease.) The laterals will need a lower Vds to turn on, and can certainly get by with less source resistance.
Put one of these inside the chassis and you’re off to the races. Should work perfectly and sound fantastic.

I hadn’t really considered doing a layout for the circuit itself, but who knows. That said, Jim’s suggestion is a good one.
This piques my interest (even more than the ACAmini on its own)!
I could repurpose my Hitachi HMA-6500 (with j48s and k133s) into an ACAmini…

Hitachi is going to be just warm, Hafler not even that
in any case - both of these better to combine (using original mains xformer and outputs) with latest Stasis FE and make big amps
for this mini ACA , small case is part of the game ........ and both of these are just .... not important being overkill, but being clumsy in size ....... not cute anymore
of course, just my opinion ( but we all know that my opinion is only truth)

Dangit, ZM… You know I was eyeing the Stasis treatment, too…
So when are you gonna make your 6500s Stasisissified? 😀
Then you could find all the warts before I proceed. 😎

dunno mate
I'm certainly not lacking projects in progress, and that one is awaiting proper moment of lunacy .......... what is important is that I disassembled functional amp in pieces long ago and it is just waiting
no biggie, it sounded as crap anyway
edit: is it thing to worry about - I'm still immensely enjoying wild disassembly

Got mine today. Unfortunately, I’m off to travel to Albuquerque to see the ballet this weekend, so no time to build. Work still interrupts my days, so this little project will have to wait until next weekend (or some evening this week if I can muster the focus).
Looks like it will be fun!

I'm happy to announce that all of the lottery kits have been shipped, the last being to Canada and Malaysia. Anyone who doesn't receive theirs in a reasonable amount of time can contact me for a tracking number.
Dang, this thing sounds good! Thanks again to Nelson and BAF for the opportunity to win and build one of these.
So far I’m preferring the jumper in. Really fun to change on the fly! Hope to makes some measurements soon.
