Default PCB files or toner transfer art for Toole regulated power supply for NS10?

I know that it has been (many) years since the Toole reg and NS10 discussions were very active (2009??), but I'm thinking of building an NS10 for myself, and I need to build a good power supply for it.
The artwork and layout files were mentioned in this thread:

Threshold NS10 Lineamp PCB

Apassgear and others participating in that thread developed layout artwork for the Toole shunt reg, suitable for doing a diy toner transfer pcb. The files weren't posted here but were available at that time by email.

I've searched but haven't turned up anything.

If you have those files in your computer, or have a link to them, I'd appreciate your help in getting them.

Thanks!

With my browser and viewing preferences, the link just takes me to the top of one 'page' in the discussion, so I can't see exactly what you are referring to.

Further reading seems to show that some oscillation problems never got worked out for the Toole regulated power supply, so perhaps I should be looking at a different power supply anyway, for the +24v single rail that the Threshold NS10 preamp needs.

Why don't you modify the BoSoZ power supply for one +24v power supply?
Or, the Jung/Didden supply in the store is good up to a few hundred mA?
Or, you could make a LT1083 based supply, lookup Aunt Corey's Buffered Preamp. It's has a nice example of a power supply you could mod for +24v. Just two resistors to set voltage.
Or, check out one of Salsa power supplies?
Or, you could design your own pass transistor regulated supply?

No shortage of power supplies to explore.

One of the best articles I have ever read.

Thanks for all those suggestions!
I'll definitely do some research and pick a design in the next little while.
Half a BOSOZ PS would be straightforward as I can make another board easily, but I may well try something different, choosing from your list.

Those are just some examples. Of course there are others. Find the one that makes the most sense for the circuit design.

Yes.
A lot of the straightforward (newer) IC solutions don't seem to stretch to 24v, but that still leaves a lot of choices.
I doubt I could hear much difference between the 'better' power supply designs, but it's fun to make something good anyway. If it's an elegant design, even better, IMO.
