Looking for some help on a arcam alpha 9 worked for 5mins then went into protect i tested the bias 7mv on both channels but it wont come out of protect
Yes just stays Amber I looked for fry joints couldn't find any I think it's the protection chip but I hope it's not that as I can't find that chip anywhere online
@@callum450gaming2 Hi if there are no dry joints on the output transistors, check the 5 volt supply voltage on pin 14 of the and pin 4 Z401 the Micro controller.

Is the Amplifier in protection mode?

It's the power amp only model so I don't have that chip. The only two that I can see is z501 and z3 the atuo bias chip
