if so from where and if not did you resolve the problem ?
I have what sounds like the same problem on the Intek, suddenly both channels are lost from all inputs, problem seems to rectify itself if the equipment is left for days sometimes weeks. Obviously this is not a practical solution.
the Thermistor I have replace, but the Power transistors are to hot (in approx 20 min) , also q602 and q409 to. I have replaced all this critical ZTX... transistors and their capacitors also 22µ. Power Transistors are OK and their Drivers to.
Do you or any from here have any suggestions?
no amplifiers that had the same error even before the exchange of components, so the output voltages already agree it is only my opinion warm.Ich thought to myself that leads to off after about 20 minutes
