#Aer compact 60 manual

The distributors for AER are not prepared to provide me with a schematic. It was hard to see what the value of the blown bleed resistor was - as it burnt the casing somewhat and almost took out a small capacitor (!).

Just need to also know if there is a relatively easy way to calculate the correct bleed resistor value and wattage. Hi everyone, I have had a look through articles relating to chip amps and bleed resistors. My friend says that his band member has exactly the same amp and his does not run as hot as my friend's one after an hour of playing. I am thinking of replacing the TDA7294 as I suspect it might be damaged and thus activating its protection circuit prematurely. It only shuts down when a guitar is playing through it. I could not get the amp to shut down when I was running my hifi tuner into it for well over 4 hours yesterday. This chip has a thermal overload protection built in so I think this is what is operating and causing the amp to cut the sound output (the power light stays on when it shuts down). I also found that the main amplifier chip on the board attached to a large heatsink is a TDA7294. I put a new one in and it burnt out straight away.

Not that this would affect the actual operation of the amp. On closer inspection, I found that the bleed resistor had gone open circuit.

I cannot get hold of a service manual for it so it's a case of running several tests and looking around to see what's going on inside. I am currently looking at this amp after being told that it suffers from cutting out after an hour or so.
