Hey everyone. I got one of these about a week ago, played fine. Went on vacation, come back, plug it in and it buzzes like crazy. Take your hands off the strings on any guitar ( single coils or humbuckers) and It buzzes like crazy. Change cords, preamp tube. Same thing. Gain at 10 o clock volume at 11. Any ideas?
Plugged into a crate celestian 1 x 12 cab. Planet waves speaker cab cord.

Check your power outlet?
Try a different one?
it's a grounding issue....
Does it buzz without the guitar?
If it doesn't without the guitar, guitar has a short, or cable.
So try just the cable, no buzz, guitar!
Check your power source first.
If your power source is okay and you bought it new, take it back where you bought it and try another power supply if they have them in stock. If it still does it, it's not the power supply. Find the closest authorized Orange service center. Also make sure the input jack and the speaker out jack are not loose. If they get loose they can twist and cause a short. That's probably not it but worth checking.
If you bought it used and it's not under warranty, you can probably replace it with a used one for whatever it costs to get it fixed.
Replace the power supply.
I've been running mine for a year with a leftover Dell laptop PS, quiet as a mouse.
Got it used. Worked fine at first. I think I will try and find a laptop power supply. When I got the amp I thought the power supply looked cheap. I wonder why the couldn't hard wire it to the amp.
Ok dumb question here. I'm considering the MT and the 2x PPC108 "stack" option... on the back of the cabs I only see one jack, so how are you guys daisy-chaining them? (sweetwater pic)
I actually called orange and they said this is now by design. They realized the load was causing problems so they removed the extra input. Some retailers have old stock from when the can has two inputs.
So I guess that means you shouldn't use the "stack option"?
Or, How was the original plug plate wired? series or parallel ?
I don't have that issue with my Micro teror rig, MT, 6" Vox Bulldog, Alessis Nanoverb.
I just remounted the nano-verb to the side from the stealth placement on the back. I was using the verb as a set and forget reverb but my buddy was playing around with the knobs while we were jamming, so I made it easier to use.
