    Peavey 600E amp/mixer

    This amp/mixer has a loud hum at turn on. I can't find any diodes shorted in PS. Any other ideas?

        Replace the Main Filter Capacitors. They may be 330uF 450V or thereabouts.

          Is this it?

          You can also check the regulators on the power supply, I had a hum come fron blown regulators before and you they don't always go dark when they do

            What Zener Diodes on a Linear Power Supply
            by caspian
            Dear members,

            I have a linear variable power supply with unknown brand name that I used for voltage injection.
            Then it failed. I discovered that its transistors (Q1 and Q2) are shorted.
            In addition, I discovered that its zener diodes are defective.
            I can replace the burned transistors.
            But I do not know the model of the zener diodes. the model number is not marked on the zener diodes.
            Therefore, I cannot replace the zener diodes.
            I do not want to test the zener diodes in a test circuit to discover their model or value.
            no schematics are available...

            Schematic Digital Audio mixer RCF type M18
            by Bektronics
            Hello dear audio friends.

            I am feverishly looking for the full electronic schematic (not a block diagram) of the RCF type M18 digital audio mixer.
            The device does not make a WIFI connection with my Apple tablet and yet I have already installed the recent app on it.
            I suspect that there is a problem in the mixer itself with the WIFI card and of course I would like to see this on an extensive schedule before opening the device.
            Thanks in advance if anyone can help me with this schematic.
            Of course, all information about this digital mixer and possibly references...

            Philips 43PUS7506/12 - Loud blown out sound
            by aidanmo
            Hello,

            I've got a really strange issue with the speakers on my Philips 43PUS7506/12. It makes this awful loud buzzing now. It happened after it was attempted to be wall mounted - I think the back got squeezed and something broke.
            I thought maybe the speakers got damaged, so I replaced them - no dice.
            • Using the internal speakers, it always happens.
            • Using the headphone jack, it never happens.
            • Using the digital/optical out with a soundbar - it happens after about 2h/movie runtime - it's never as drastic, it just pops in and out, but I didn't want it to damage the sound bar
            ...

            Yahama mixer PSU difference
            by Thermaltake
            I am planning to buy myself a new mixer. Yamaha MG12U or XU(not sure) and I always like to take a look inside of mixer to check how it looks, if caps are low quality and other stuff.
            I manage to find some teardown video on youtube but video name is saying MG12XU, but when you look at video on mixer it's MG12U.
            And when I google those two models they have different PSUs one have cheap low quality caps, and other is way better with quality ones Nichicon. So I am confused now from what model exactly is that better PSU??
            I google a little and found that there is this part number...

            Power button on Behringer Xenyx 1204USB mixer dead ?
            by Thermaltake
            Hi, I got Behringer Xenyx 1204USB mixer, and in the morning mixer was working fine, but when I came home from bike ride I turn it On but nothing happend. Phantom switch is working because red light is On, but other switch no respond.
            I brought mixer to my friend today who is electronic expert and he will tell me if it's the button or something on power supply that died. But I am 90% sure that it's power button. My question is, is it possible to put some better quality switches on that mixer than the ones mixer came with, I found them very cheap and low quality.
