I don"t know how this happend but this is an answer for a Jeep that was stalling out. The question had nothing to do with an amplifier. Guess fixya screwed up.I don"t know how this happend but this is an answer for a Jeep that was stalling out. The question had nothing to do with an amplifier. Guess fixya screwed up.

There can many causes. You may have an amplifier damaged, power supply issue, on and on. If you are interested in having your Konzert repaired, please visit my website at audioserviceclinic.com. You may contact me there.
A faulty volume potentiometer? Some internal cross-talk? Free wires induction because they are too close, inside? It sounds possible to me and a minor problem. Don't worry too much.
200 watts is the output, home use or commercial? not a good amp to run at its max as it has a low reserve headroom. for home use 100 watts rms is more than enough.
It depends on the impedance of the speakers, if you use (2) 8 ohms speaker on each channel the load will be 4 ohms if you use (2) 4 ohms the load will be 2 ohms , check and see what load the amp can handle.
pls check burnt resistors, if ceramic it's value is .25 0hms 5 watts, if big carbon film resistor it's value is 10 ohms 3 watts. check also power transistors A1941 & C5198. also check driver transistor A940 & C2073
Hi,
upgrade your 302 to 502 need to replaced the toroid transformer, set of output amplifier, set of electrolytic capacitor.
Purchasing of these parts one-by-one is much expensive rather that you buy a brad new Konzert AV-502. Also upgrading the unit is quite tech and need a lot of experienced in electronics.
Hope that it may help you.
Have a nice day.
