Volume has started to fade
If the problems are intermittent, then the amp will most probably be suffering from dry solder joints. This is not uncommon about power devices in the unit like output stages and power regulators. I suggest that the amp needs to be checked over for such problems, and where needed resoldered to bring it back to a reliable state. If you are a gun with a soldering iron, you could do it your self. For this sort of work, I prefer to use solder with a 2% silver content as it produces a mechanically stronger soldered joint, and has a higher resistance to failure from the rigours of heating and cooling that constantly happens in amplifiers. If you think you dont have the skills required(good quality soldering is an practiced, and aquired skill), then get it into a decent repair guy for some attention. If you dont fix these problems,new faults may manifest themselves, and even expensive failures to output stages if left unattended.
