Is it well documented?
I wasn't aware you published final schematic to the public....
The threadstarter wants to use a trafo for 40 V DC per rail.
If he wants to use the case of the Denon 495...-)

You have not heard it. Have you seen the measurements?
I am feeling sick just by reading your nonsence.
You are in my ignore list now.
What about Ska 150 amp? I have 6 empty pcbs. My friend told that it has some problems so i did jot build it but i am curious how it sounds. He says resistors at Vas gets very hot. He says he used 10k instead of 2 pcs of 4k7. I now looked at schematic and problem may be because of this.( power dissipation)
I looked at chip schematics and they are also very complex inside the chip. So how can they sound nicer than complex discrete designs ?
Indeed, some Chip Amps may be good options but your rails appear to be a bit too high. You may experience problems with heat transfer too. You may use this Chinese variant of The Blameless (see the image below). I have measured it and it appears to be fine for such power supply. It has low heat dissipation. Distortion is low and frequency response is fine. It is almost verbatim copy of The Blameless with all transistors still available from trustworthy suppliers, if you want to be sure everything is fine.
Good luck.
Hi. I already bought these blameless clones and waiting seller to ship since Sunday. He marked as shipped today but no tracking info yet. I will make 2-3 amplifiers including Tda2050 utc ( i can supply it cheap here ) Lm3886 paralelled which i bought many years ago.And blameless amp. I found 2-3 more transformers. I should rewind toroidal one and I will make case for all.

There is power supply connection at both left and right on lm3886x3 board. I checked and see they are paralelled so why they do it ? For connecting them to themself?
Build an amp that has dual pnp npn input stages and opposing VAS stages. This gives the most open sounding amp I have heard.
Wolverine looks good , however it s based on the Badger which is a very similar design as the amp I replaced.

Wolverine = $$$.
I have cheaper designs that are less $$. But just as multi decade stable as badger/wolverine designs.
A small Wolverine type design with even a single pair OPS would beat any OEM out there - easy.

Here is a nice simple one .... .01% 20Khz/8R . not bad for 1980 type designs.
A lot of english companies used this to power Hitachi lateral MOSFET output stages. Works swell with a standard EF2 !
The THD this does have is H2 dominant. Cute amp.
