ACA amp with premium parts

The larger SMPS (like Meanwell RSP series) have current limiting protection mode instead of (the awfull?) hick-up mode. That is great when you have very large caps - I have 56.000µF in one build like above.
Protection type : Constant current limiting, recovers automatically after fault condition is removed
So when the cap is full it starts to offer a stabilized voltage.
 
hi TA

Can you give me a hint please where the pcb from Rudi can be found. you refered in post 1385?

is here a PCB -gerber available about ACA with TA mods?


sound after amyalice -SMPS filter:
i want to share my experience with this SMPS filter:

my setup is still small. i use a meanwell LRS 24V/150W SMPS brick in a seperate housing. I filtered every channel with this filter. the rail on the amp pcb is 24V and the DC point is 12,5V. i use the zerozone pcb with TA mods in a small chineses housing with 1,5A bias . MOSFETS are IRF044N and i am happy with the darkness of the tuning.

you should try this !!
