CRC Power Supply (Class A amplifier)

This looks correct.
But please do isolate those other secondaries, so that nothing can touch them.

@mle, thanks for having a look. I am just proto typing to prove it works. Will absolutely isolate them. They have shrink tube on the ends already.

Now in stereo with low ESR LC cap bank. Believe it or not this is being used as a very powerful headphone amp to drive up to 4w into 50ohms HiFiman HE-6.

Can you share some more info on your ESR LC cap bank, schematics and/or connection diagram would be nice to many, thanks a lot!

That is actually a cap bank layout by @prasi
- you might want to ask him if it’s available.

It accepts a N=20 of low cost 1000uF and since they are in parallel, the equivalent series resistance is reduced by dividing the single unit ESR by N. So if typical ESR of standard cap is 65mOhm / 20 is 3.3mOhm ESR.

There is also a provision for a CMC (common mode choke) and some resistors to help clean up the noise in the PSU.
