K8060 doesn´t work

Hi, i build this Kit K8060, the Power is 2x30V, the Capacitors C12 C13 replaced with 4700yF 63V, the LED worked, The Bias is 10mV ± 1%, ZD1 Power at 9V

Soldering is ok, no shorts etc. All Parts on the places.
Power Trans are cold.
If I give a signal from the headphone output to the amp, is the Output from the Amp only the power from Headphone Signal.
What is wrong… where is the Problem?
For help, I would be grateful

Sorry, this is difficult to solve from a distance.
Can you provide links to pictures of both solder- and componentside, so that we can take a look and maybe provide some feedback?
