You need to do like this 🙂
Module board
Alu Case
PSU
Connectors (RCA, Micro JST, RCA, Banana plugs)
AC Filter
Option : Volume pot
and LOTS OF PATIENCE )
For the Shui Yuan board, can I simply do the following?
* wire a DC Jack to the DC terminal screws
* connect speakers directly to the green Phoenix terminal blocks
* connect a 3.5mm jack to the input terminal via a voltage divider or volume pot
* power it with a 24v charger
Or does it involve some extra inductor/capacitor circuit?

Hi,
*You can wire a DC Jack, pay attention @ quality ! need a good one (6A at least)
*Speakers must be connected to the Green Speakers inputs (supports 4R / 8R)
*You need a 3.5MM jack to JST connector better (check : TINYSINE Cable Jack 3.5mm Stereo Femelle vers XH 3 Pins - Audiophonics)
*PSU 24V / 6A OK ( I guess you mean a Brick PSU)

Thanks for the reply. Yes, I meant a Brick PSU.
The 3.5mm jack to JST connector would be perfect.
I see in my 3e audio CLIP_OTW leds start flashing in rythm with bas when I crank it up to 50% from computer, not extreme I think just loud.
Have an Mean Well lrs-350-36 and wonder if I change the four outcaps 4x2200uF to something bigger maybe 4x3300uF would do something?

These on-board bulk caps should be of good quality and low-esr type, that is all what counts. Increasing capacitance beyond some 1000uF together with a smps are counter-productive. Btw I designed many amps and smps from scratch and consider all these anecdotes concerning the sound of caps utter nonsense.
I see another module between psu and amp what is it?
Do u have links of psu, module etc?
Thanks
Hi
I already shared details a few pages back ;-)
The little module in the middle is an AC Audio filter

Hi! Daniboun.
Your implementation is not too well within the rules of the art.
Your mains filter is too close to the op amps and the signal cable which flies above the power supply ... (high frequency).
I would have put the whole AC part behind ...
You make rest 😉
Don't worry about it )
I made some test before doing it. The fact is : the amp is working fine, no interferences in the signal path, everything is clean and even connected in BT, no noises = nothing to complain about so ) I just bypassed the volume pot and it is even better.🙂

Hi,
Not sure I will have time to review. I am really busy these last days with my Purifi project..
For the price, this amp is a safe value and sounds amazing as the Shui Yuan.

It was a jest
Hi Dani
It was a jest, keep up the good work. I've found out that it's due to material costs increase but postage is comming down from China.

I compared it to the Fx 502s in terms of sound and also measured distortion.
At a power of 10 watts, THD has 4 times more, with only the 3rd harmonic.
Sounds harsh and tedious compared to the FX 502s. Both devices are original, without alterations. Power supply 24 V.
