Denon pma 737

I left my Denon pma 737 on for 12 hrs by mistake and now there's nothing but low signal and static. Can it be repaired?

    I have the same problem. It has been years since I have plugged it in, and I have assumed it was a bad power source. Is this so? What can I do to get my baby running again?

    Check the four 3.15 amps fuses near the output transistors

SOURCE: my denon amplifer was playing okay then the trebel

Determine if it is both left and right channels. If it is then you are looking for something that is common to both channels as the cause. It could be something to do with the tone circuit, perhaps an IC, another suspect is the bias section. And if only in one channel then at least you have something to compare it when seeking the fault.

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: Denon Amp (PMA-700AE) ignores the signal from CD Player DCD-700

If you can follow the circuit from the input of the cd play socket inside the amp itself you might come accross a Memory Retention Capacitor that supplies an IC. If you do. I can't for certain say one will be there, I would replace it, it might be the cause of the lost memory of your device.
If you don't know what a M R C looks like, they are like electrolytic types, but haven the appearance of being squashed. The value will be low only 0.22uf etc and the volts very low say 5.5. The PC board marking will be different to a normal capictor.

How can I connect a subwoofer to this device (denon pma-520) http://www.hifiengine.com/manual_library/denon/pma-520.shtml?destination=node%2F14208


The only safe way to do this us to connect the sub to one of the other speaker outputs using a "speaker selector" switch. For example, you would go out of the receivers left speaker output, into the selector switch then out of the selector switch into the sub and the left speaker. There really is no other way.

Although an updated turntable with USB can be used

without the need of such RIAA phono preamp.

I have a denon pma 500v amp, has distortion in right channel, both speaker output and headphones, what should i check for first?


Just have a look around first. Remember the left channel will be the same as the right, so if it doesn't look the same in the right as the left you have the cause of the problem. Resistors are good at causing it, but transistors can too.

Denon PMA 700 AE maximum phono input signal


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.

I am getting static out of all speakers in my Denon AVR-682 Home Theater system even at low volume. Connections and speakers are all good. Where do I start to look internally for a fix?


Static could mean a few things.

Magnets on or near (tube TV's) the system could disrupt the signal.

Try plugging the speakers in one at a time with music going to the AUX in. Run through all your settings to make sure that nothing is abnormal.

If it's plugged into a powerstrip, try plugging it into your wall outlet.

201-762-6500 is their main number.
