Hi Luked
Have you tried contacting sellers of Shengya gear? Maybe they can steer you in the right direction or give you the schematics or service manual you need.
Here is one e-tailer that has sold Shengya stuff for some time.
www.cattylink.com
service@cattylink.com or info@cattylink.com
From looking through the A'gon Manufacturer directory here is the contact e-mail I was able to find from there
info@shengya-audio.com
If you have tried these avenues already with no luck my apologies for the duplicate info.
