Is it the resistors near the relay? that would be 10 ohms. You may replace it with a higher wattage (like say 5 watts)

SOURCE: Konzert AV502a (500watts per channel)

Your listening habits should not have you pushing the volume level so high that the amplifier will distort, as it is DIRTY wattage that kills speakers. A more powerful amp will distort less if pushed to a given loudness.

BTW: the specs for the amp and speakers are not really what they claim. Since the same company made them the numbers are probably equally wrong. Don't sweat it and don't turn it up so loud that it distorts.

SOURCE: how can i upgrade my av 302 to becomes best as

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.

What would be the probable cause of my konzert amplifier av-502 after replacing 2 power transistors npn & pnp in the left channel, the sound is distorted. i'ved checked the voltage across the spea


Check the bias resistors. They can burn out when power amp transistors fail. They will be very near to those two replacements. You can compare any parts using the right channel as a good. Readings and voltage measurements should be the same for both channels. Also the look of the parts. If a resistor is off-colour in the left, but not in the right you know something is up.

Just asking for a right speakers for konzert 502a


What actually is Right is for you to decide:

These will be dependent to what you intend to use.

If these unit will be used for Karaoke , suggestion could be

using Single 15" Konzert Speakers for each channel or

Dual 12" Konzert Speakers for each channel.


But if you intend to use it in a small room , you can visit the

showroom in which speakers are connected to it, to have your

final decision.What may be best for others may not be the one

you choose.Listen and feel what you like .


Have a nice day!

If you intend to DIY , check for possible cold solder joints,

leaky transistors , changed-value resistor.


Upgrade to 502 it is better than the one you have.

MTX 502 2 chanel amp Pre amp problem?


Unless your amp is 1 (one) ohm stable then you may have fried it. When you attach a 2 ohm load across a bridged amp then you have effectivly placed each output channel on a 1 ohm load. Not a good thing in most cases. Try hooking up ONE speaker on one channel and one input to that one channel one at a time. Then switch the speaker/input to the other channel and see if you can get either or both channels to work independently. Needless to say you must turn the amp off before you make ANY change in the wiring.
