boards
Hey Chris, I am from just north of you Fox Valley area.
I have a DIY PSU board to help you out.
PM me your address and I will hook you up.
Good luck with your builds and I did say BUILDS.

Will do. I have to go slow. The store is out of PSUs.![]()

Thanks Greg. You’re very generous! Message inbound.
If the PCB ever gets a revision, C6 C7 will be removed. They are not critical at all.
Good news. Reckon I'll keep the order in just in case (they're fairly cheap), but won't count on them being here to move forward.
Ordered the 5U metal box today. Spendy little buggers, aren't they? But the convenience of them being predrilled and part of a DIY "system" makes it worth it for expediency of build. And since it's coming from Italy, it's super exotic and stuff.
What is this Mini?
It is just using the Aleph 30 with a single output pair. Here is my amp and running at lower voltage rails typically.

Great look!
My plan in the near term is to build this amplifier and see what kind of magic I can drag out of my Klipsch speakers. I also love woodworking and plan to put together some of the Onken style speakers from Planet10. I’ve never done anything with full range speakers before and it looks like a fun experience.
For larger projects like a Linkwitz LX521, I’m quite sure the Aleph would be suitable for the smaller drivers based on what I’ve been reading about it (even though Link suggests 80W per driver). Is the Aleph suitable for those humongous 10” bass drivers they specify or is there a better option? In multi-amp configurations, of course. Definitely future state stuff. 🙂
Edit: I just re-read the LX521 description
“The LX521.4 can be built DIY from a Kit for around $3300, including a miniDSP 4x10HD equalizer/crossover. Additionally, the speaker requires between 8 to10 power amplifiers of 50 W to 200 W. ”

yes, the LX521.4 is a unique speaker with most all drivers having their own amplifier and active crossover. Most builders use Class D amplifiers which can be more compact than 10 class A amplifiers. The Aleph with be a great match for the full range onken as I am sure they will be for the Heresy's too.
I’ve heard depending on the type of music and volume being played, the Linkwitz LX521 bass section can be a little greedy. I’d be looking at a M2(x) for chill volume levels or BA3, Stasis or F5 turbo if louder volume levels are needed
I’ll just stick to the Onkens for a while. In the plan set I bought I have at least two or three dozen designs to go through before getting tired. 🙂
As parts slowly trickle in, I'm planning activities in my brain so that I can do this efficiently. While I didn't see anything about it in any of the documentation, is there any need or benefit for the amp to be connected to a dummy load during testing or alignment? Or is everything done open circuit?

both input legs grounded, no load on output

Fabulous.. Thanks. 🙂
Chris, did you get your PSU boards today?
I didn’t see it in the mailbox today. Maybe tomorrow. USPS hasn’t been the speediest as of late.
Tracker shows it in Oak Creek. Should be here tomorrow. 🙂

before wiring and even mounting in the case, post big well lit pics of boards, so boyz can confirm that you did well with several optional positions
it could save you later trouble

Chris,
R8/LTP Bias can be replaced with a 1K ohm resistor should you choose. And R27 bias pot should be set to 68K beforehand.
Best,
Anand.
