SOURCE: Denon PMA-520 amplifier clicking noise

Sounds to me like a bad capacitor, but not sure. I would look inside for any slightly bulging capacitors or capacitors whose plastic wrappings have melted or shrunk or cracked (most caps are cylindrical). Please unplug first and be careful inside there and do not touch anything. I actually came across your post while looking for info on what I think is the same amp my brothers had but blew, and I was going to ask if they still had it so I could repair it. I've been very successful at repairing my electronic equipment such as Altec Lansing Model 95 speaker crossovers, power supply in Emu Emax II, and almost everything else in my studio.

SOURCE: konzert amplifier av 302 theres an echo sound even I can change all new all the IC and variable resistor on the mic amp all so the capacitor besides at the echo sound but if I can turn off the echo it

Check the ignition coil, they will often heat up and then produce no spark. Are there any codes present? Is the check engine light on?

Konzert amplifier av 302

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.

Konzert amplifier av 302 can i use 4pcs of 200watts speaker in that amp

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.

6691d32f-b8b6-48f0-a192-f26a488dd4dd.jpgDoes the device use a single IC power amp for the main power amp? Look at the big heat sink, if you see something like this it will have failed. But if you see lots of individual parts there check the pre-amp stage first. Looking for something common to both channels.

Konzert AV502a (500watts per channel) + Konzert 600 watts speakers Will I not have problem with this setup? I heard that my amp should have higher wattage than my speakers.. Pls advise..

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.
