Can I use 12-0-12 volt 7 ampere transformer to the power supply board? How will be the audio output after that?

It works well with the 12-0-12V 7-amps !!! 12-0-12V 5-Amps low output

Hi, can a 32-0-32v, 5-amp dc power supply be used to connect to the power supply ?

no. this needs 12v dc power supply.

Amazon Services Good, But T&TT Products #KACHRA

Delivery and shipping are good by amazon but product quality so cheap. In only under two months some components damaged while playing sound like one 3055 transistor and some resistances with capacitors. My money wasted. So never buy Tech &Trade products its only waste of money.
