Mooer Preamp Live Repair - Part 2

[@TheAaron3dg]

Great video! I really enjoy watching the troubleshooting process, it helps a great deal when I run out of ideas on a dead pedal

Nice repair. Any thoughts on a unit that powers up and functions properly but with no sound? I have proper voltages and audio probed at the 4272 input, but not sure where to go next.

I've just tried replacing two blown capacitors, after watching your video and identifying two blown out capacitors on mine. Two 100 mA ones had clearly blown out. I've just replaced them with the same value caps. The unit switches on and goes through its light sequence ok and it still connects with the app. The issue is that no sound is coming out of it at all. Do you have any ideas what could be the problem mate? Great channel and presentation. Carlo 🎸👍🏼

If the 2 100uF were blown it's likely that the other ones are blown also. I had to replace all of them. Check the voltage at the DC to DC converter and at least one or two of the op-amps like I do in the video. Probably there's no voltage going to the op amps.

It seems like a lot of these Mooer Preamp Live pedals have just randomly died on people. Do you think there’s some inherent design flaw that Mooer never addressed? Do they use caps that are prone to failure?

Email me with a description of the problem. Thanks

I just had mine go out. If you are still repairing them, I may be able to send it out.

Hello. What small smd zener diodes are mounted on the board? I had one blown off by a hot air station and I don't know the label.

[@signalsandbits]

Email me a picture and I'll find out
