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... |
