Does anyone have or know where I can find a board that would let me mount a single or side by side Amveco PC mount low profile toroidial transformers? I'm just looking for a board that would have AC in and out going to terminal blocks and allow the use of standoffs.

If not, I'd gladly pay someone for their time to lay out a board for me. Something like the pic in here
should I socket the LED's? I remember doing this on my original Dynahi to get the offset as low as possible.
Here's the latest with LED and cap changes

You're right, I had wondered if those LED's were wrong. I've swapped them for what you posted. For the 5pF I believe it's 5mm but will measure again tonight.
Back when I built the original Dynahi I had to swap out LED's to get the lowest offset IIRC. Is that the case here?
I noticed that some are using a better quality resistor for the 20R. I was thinking of using Takman in this spot. Does it pay to use something like Takman or PRP in this spot?
Finished the BOM, I'm pretty sure I got it all. This is for one board.
Take a look and let me know if I missed anything or there are better part choices

Yeah, I realized that about the PP 4.7uf early on, just thought I was missing something. I'll swap the electrolytics out for these https://www.mouser.com/ProductDetail/667-63SXE100M
So I can definitely leave the 4.7uf film caps unpopulated then?
I can't seem to find Wima PP that fit at Digikey or Mouser. I can find PET though, will these work?

I thought about the parts I have for building 30V GRLV boards for my dynahi, I noticed that the tantalum caps are all rated at 25. Should I increase them to 50V when building for 30V?
I'd agree... I was quite pleased when I fired it up. I'm inclined to just leave it.
Compared to the TPA bipolar supply it immediately sounded better. The sound stage seems more dynamic and I hope it gets better.
