Default AT-HA-5000 schematic

Hello,

I am planning to build the HA-5000. Now I can order the pcb from the famous Chinese websites, but I'm looking for the complete schematic. On the internet I do find schematics of the amplifier board itself, but not of the power supply and overvoltage protection. Hopefully someone of you has the complete schematic and possibly the parts list available.
Thanks in Advance

I have seen many "basic" signal circuit sketches of the Audio-Technica AT-HA5000 headphone amplifier, but not a complete schematic.

Can you share what you found?

It is a little bit more detailed than the schematic in you link.

Thank you for sharing your find. It would be nice if we have the actual Audio Technica service manual.

Ebay seller usually does not share the schematic of their kit.

A Service manual would be nice. But unfortunately I have not been able to find anything so far.

One step further in the process. I found en check the protection and relay circuit. Unfortunately without values, but it is possible to identify by the color codes of resistors.

I have just made a rough draft of the schematic. I have drawn these from the PCB board. Unfortunately without capacitor values. Note, I'm not sure yet if this 100% is correct, but it is a start.
I like to hear your thoughts.
