Default Problem with Charlize amp

Hi guys,

Decided to ask for advice...

I bought an used Charlize amp from someone here on the Trading section and after a few months of keeping it in the closet I got to trying to make it work but it does not want to produce any sound.

The configuration is the following :

-a sigma 11 power supply from Amb labs - works flawless and puts out exactly 12 V, as specified
-Charlize amp module as seen on the site (http://diyparadise.com/charlize.html)


Now what I do is connect the PSU to the Charlize, then I measure 6 V on the output and 2.5V behind the input capacitors( on the legs of the TA2020) but when I put a sine wave signal on the input I get nothing on the output, no noise not even hum on the speaker...

Am I missing something? And should I check something else or add something else to the chain? Please advise...
