İ have a unison research sinfonia.
I broke the reg right and reg left cards of my amplifier, e-mail the company and what I wanted, but they did not answer in any way, urgently need someone to help me
I need my amplifier's service manual
thank you very much in advance.
Can anyone give me advice on how to change the fuse on my Unison Research smart 845 monoblock power amp please. Or point me in the direction of someone able to repair such a beast. Many thanks.
