One way to deploy an AC-to-AC wall wart, is to generate a bipolar plus-and-minus "voltage of your choice" using the VRDN board (here) on diyAudio. Wall wart in, ±15V (or ±12V, or ±18V -- your choice) output.

I'm just pity performer of drawing works ....... and my involvement stops there......... well, except - contributing to Help-desk later is sorta logical
Meaning - all about time frame, quantities, exact form of kit package and price ......... not my area

Reason why DiyA server crashed was .......... server tried to make AI of me, and then tried to find something I don't know, hoping to reason with me
And then server crashed

Guys, transformator for Aleph J - 300VA min, 18+18V right? And amperage? What kind case for him I can find on Aliexpress?
300VA , 18Vac+18Vac
yes, practically same figures as original Aleph J, one xformer for PSU common for both channels
VA divided with V will give you A, but what's written in first line is exactly enough for purchase, so you don't need A figure
case - for amp or for xformer?
if for amp - take Modushop 4U/400, or at least look at that one (overall and especially heatsink dimensions) as exactly adequate, if you can find something similar

Yes. Maybe even for two monoblocks (case like my Cyrus).
Amperage is same on the wrappings or different?
Can I see the example?
see at linked Modushop site, their Monoblock cases, Disipante series
clarify question about "wrapping"
if you're asking about First Watt original xformer - wrapping - well - you can trust me or not
or go to 6moon site and look at First Watt pictures

as I said ..... here are two examples of adequate xformers, having all necessary info:
-300VA, 230Vac primary, secondaries 18Vac + 18Vac
-300VA, 230Vac primary, secondary 36Vac CT (CT means - center tapped)
differently written, same xformers:
-230Vac primary, secondaries 18Vac/8.3A + 18Vac/8.3A
-230Vac primary, secondary 36Vac CT/8.3A
it's clear when you remember that VA=V*A

Hello ancient dodos. I hope that you are doing well those days, x-mas coming up and all that. Just popping in to say hello. Im doing experiments with concrete cast pipes filled with damping and REW, for room treatment. As for now I cant even see a difference when measuring in the pipe opening. New experiments tomorrow, stay tuned for more rock’n’roll
Thanks friend, likewise! I think I have found the trick for a bass eater. 25 cm diameter cardboard tube for concrete casting, 90 cm tall one end closed. From top: 1. No tube. 2. Tube loosely filled with isover up to the rim. 3. Two grabs of isover in the bottom of the tube. 4. Empty tube with a fleece blanket on top. Just need to cut it a little more and ditch the filling. Cheers!
