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.

Well, it seems you have your finger on the source of the problem. If accessible, try some tuner cleaner inside the potentiometer.

Why? Are you contemplating connection of something OTHER THAN A PHONO CARTRIDGE to it?

Be advised, only a phono cartridge should be connected to a Phono input. There's more going on behind it than just voltage step-up.

Denon PMA 250SE does not have a RIAA phono preamp.

for some info about these preamp and details here;

for these preamps.






Although an updated turntable with USB can be used

without the need of such RIAA phono preamp.

My Denon PMA-900V integrated amp has distortion in the left channel. When it is cold it is very minor, as it heats up and is played at louder volume the distortion is much worse.


The good news is that it's in one channel, which means you have the right channel parts to compare it with. Now the bad news whatever causing it and it's likely to be a semi-conductor (transistor or IC) has to be replaced. However finding it is easier than you might think. For a start it's going to be hot to touch. And you can get get it to stop being hot, while the amps on, so correcting the fault, for a while. You do this by spraying it with Servisol Super Freezer spray. You have to have the amp running for this. Find the left channel amp and wait while it goes bad. Then spray (one at a time) any part you suspect. If the sound returns to normal, you have found the faulty part! To prove it spray the same in the right channel. That shouldn't change.
You can get the freezer spray from your local electric parts shop (such as Maplin UK).

Hi , I have a denon pma-2000r amp in it stuck in stand by mode, i don't have original remote control, is it possible to turn it on without remote control or reset to factory settings? Many thanks!


That model shouldnt be stuck in stand-by
Are all the speakers connected?
If it wont properly turn on then there is a fault being detected. Could be disconnected speakers / bad speaker or a power supply issue

Hello I bought a Denon PMA-500 Amplifier. When I turn it on the light indicates on for some seconds and after that is shuting down (goes back on standby). Do you have any idea why? Thanks for your...


it could be that there is a kind short circuit , check that the speaker wires are not touching each other the metal part should be max 1cm long , and check that the plus is connected to the red clamb and the min to the black clamb , check also that it can loose it heat

if it still doenst work it must be sent / brought to a dealer
