How to Revive BOSS PSM-5 Power Supply and Master Switch

BOSS PSM-5 Power Supply

Dear fellow guitarists, let me quote my previous article about my BOSS PSM-5 Power Supply & Master Switch which I almost discard providing it would not operate normally as it should be. Quote:

Secret About BOSS PSM-5 Power Supply.

BOSS PSM-5 Power Supply & Master Switch I am telling you about has to end its service to me in two options: first, I will give it a last shot by drawing a direct wire to an external grounding source. If the loud humming could be cured this way, then I will keep it.

If not, then it must go to the second final option: it has to go to the garbage bin. Cross out the store where I bought it from and I will ring another friend whose musical store is now getting famous in town to get a new fresh BOSS PSM-5 Power Supply & Master Switch.

I did him call asking for a new fresh BOSS PSM-5 Power Supply & Master Switch, he was not in, one of his storekeeper answers. I pass the request to him getting a shocking answer that BOSS PSM-5 Power Supply & Master Switch is discontinued.

After calm down, I took a look at my legendary BOSS PSM-5 Power Supply & Master Switch and start thinking to myself. If it has to end this way then let it be. Let bygone be bygone. Before I said goodbye to it, Professor J’s last words before I left his place popped up in my mind and ringing in my ears.

  • ” This system relies only on this point as its grounding contact…”
  • ” This system relies only on this point as its grounding contact…”
  • ” This system relies only on this point as its grounding contact…”

I hope you can see clearly this a bit out of focus pic of my BOSS PSM-5 Power Supply & Master Switch showing thin flat washer and nut I removed from the Amp output socket. That should be the exact point of these nuts that drive me nuts!

That is exactly the point “Professor J” showed me that evening. They are supposed to build a good surface to surface contact to the 1/4 mono plug at each of the BOSS PSM-5 Power Supply & Master Switch Amp and Guitar output sockets. I wish I have a better cam with me to take a macro pic of the rotten rusted surfaces and edges of these nuts.

The tiny red straw is of rust remover spray. I washed clean all of the BOSS PSM-5 Power Supply & Master Switch Amp and Guitar output sockets by spray rust remover agent on and wipe them clean with tissue paper some 3 minutes afterward.

Pay special attention to clean the threaded section, rust, and dirt perfect hide. I gently rubbed the thin nut and flat washer on extra fine sandpaper soaked with rust remover liquid. I do not have to show you how melted rust looks like, right?

Slowly crank up the volume knob and I wondered for a second if things were getting worse instead because I heard nothing out of the speaker. I was surprised it was at 9 o’clock position and I heard just a quite soft hissing like a snoring kitten. Rather than the used to be barking humming noise.
