You are number 11 but I’ll give you the heat spreader since you barely missed it.
Micro-audio PS users that have added the extra capacitor bank feedback?
I want to build at least two of these amps, one basic and one with upgraded op amps(though know it might not matter), extra caps, etc....I have 4 boards coming partly to help get the GB done and partly as I might want to build a few amps but also I was considering mono blocks as well which I still might do though it would be some time from now, too many other more critical projects in our all out remodeling of our full time RV.
Edit: I just noticed the Mundorf cap option on the PS itself, anyone tried it that way and or with the added capacitor bank?

I just have a life long habit of modding things no matter how good they are, not sure a blessing or a curse. At least most things can get better with a few or a lot of mods but sometimes.....like now, starting out with a superb design........
How about any of the caps on the board, any upgrades worth doing? I do not mind spending quite a bit on a few caps if so, at least I get to have some fun like in likely using the 1642 op amps at least on one board.
Or, the Mundorf cap option on the PS?

Just got the boards, very fine indeed!
In 20 years in Military electronics I have seen a lot of circuit boards and these are as good as I have ever seen and better than many.

There is an issue with the BOM. Some resistors are not specified in the correct size, should be 0805 instead:
I am only passing this on from the Romanian solder slinger, so not sure if there are more parts like this.

Hi xrk
Just placed an order for board and heatsink coupler, 3713236854.
Let me know when you think shipping is possible.
Thanks

Sorry that there seems to be a mixup there. I have never had this error reported before, and in fact, hundreds of boards have been produced with the correct part. The BOM shows R1021-1024 as 22R 1% Thinfilm 0805. Please see screenshot below.
Perhaps we can verify the version of the BOM that builder in Romania is using. But I see that maybe the confusion is the part number specified points to an 0402 part. That is clearly an error in the BOM.
The schematic shows this as 2k2 0805. I do see that there is an inconsistency here.
