Indeed, Neurochrome's soft start is Rolls Royce. All features you could think of and max 2kVA transformer. A beefier standby supply is about all I would want (0.5W is a tad weak). Adjustable LED brightness is a very nice touch.
The diyaudio speaker protection board simply requires the appropriate AC voltage. I believe the power supply is on the speaker protection board.
Boards have been manufactured but there may be some extras. Read first post of 5th group buy thread and send order form to Stuart and see how you get on
I see the boards are about to ship out so maybe pointless but does anyone have the dimensions of the heat sinks and the relay off of the board?
I have a little bit of time today where I can start laying this stuff out inside of my little chassis (toroids going external to the chassis)

Yeah, I'm pretty sure. I want to be able to keep the noise as far as away as possible. Putting 2 giant noisy components right next to sensitive circuits is anathema to me.
The Wolverine has been built many times with superb results having the mains transformer in the same chassis.
Complicating the build with an externally mounted transformer doesn’t really gain any advantage here.

Well, I have had an issue with one amplifier before that had a toroid. I have since shielded it and still have idle noise. Somewhere I came across a bunch of pictures of someone building a wolverine. If you go down the timeline you'll see they started with an unshielded transformer and then moved to a shielded one. Why would they do this if not for encountering noise?
These exist, they are twice the cost of an unshielded toroid. If I could be guaranteed zero noise using this then ok. However, as aforementioned, I shielded another toroid and it just knocked the noise down, it did not completely eliminate it.
Not to mention how much physically large the chassis would need to be. Here's a reference of the size difference. I could place the toroids elsewhere which would give me more flexibility in positioning of the system, they would be less noise, smaller footprint because I could use the unsheileded ones, I could 3d print the toroid chassis so I save money not buying a giant chassis (the wife isn't thrilled about a giant ugly metal box in the TV room), etc.
More flexibility

The trannies themselves do not cause any noise to the amp.
The main source for noise problems is usually the swiching noise by the rectifiers, but there are good ways to deal with this.
Keep the trannies in the chassis fir safety reasons.
The diyaudio speaker protection accepts 12vac? I assumed it was 12vdc. Does the DC speaker protection boards from the group buy, do they require 12vac or 12vdc?
Now you would have 2 chassis to deal with and more cables. A plastic housing for power transformers is not something I would do.
But, some say tomāto and some say tomăto.🤣
@Bmsluite,
You are taking your observed sample of 1 for a different design and applying the findings to this (different) design. And then coming to the conclusion that this experience is more informative than of 100's of builds of this design that say otherwise.
If you choose to use a separate chassis, do it because it's what you want to do. This is a hobby after all, and if that's what's makes you happy, do it. However, do not incorrectly assume it's going to fix a problem that 100's of builds demonstrate does not exist.
