After about 55K units of repair most of what I've seen as a repair technician is broken units. Faults occur in near everything, I expect them and they don't surprise me. The integrity of the equipment generally does get much better with higher end gear but it's not a rule. One thing I dislike about this amplifier is the use of the adhesive under the capacitors. I've confirmed several times that the adhesive there gets baked from heat , it's properties change and it turns conductive and can cause weird intermittent faults to occur or the protection circuitry to engage. I've seen the adhesive turn conductive in audio gear and also when I worked as a QA/QC tech for a down-hole tool company. (Pressure, temperature, torque, strain and tension measuring devices used down-hole at depth when drilling for petroleum.) We where dynamically and thermally qualifying hundreds of IC's at a time in a oven and spec'd them up to about 175C because it gets hot down-hole and the higher the spec the better. Both the 120V AC power and the low voltage square waves in digital circuits have been seen to be shunted by the adhesive used on printed circuit boards that has gone conductive to some degree. We had repeat problem in the down-hole tools, I inspected some used tools that where baked from high heat and after advising the engineers of what I suspected was the issue we stopped using the adhesive on the circuit boards and the issue went away in short order.
