Broken - Furman PM-8E Series II Power Conditioner

[rabidgerry]

Guy's you both are a great help.  Really I am in debt to you for always helping me out.  I mean that sincerely and others on here who are a constant font of knowledge.  I actually wish I was properly electrically engineer minded (I might take a course time if I ever get time).

MJMP totally much appreciated my man!    I look forward to getting back to Belgium with the band, or even as a tourist.  I loved that tour, it was an amazing experience.  To get to meet you then in the process of that was a mega bonus.  And to think my tone was nowhere near as good as it is now (shorter cable runs my friend  ;) like you always said) so I'd be keen for you to hear how it all sounds now I'm fully fledged rack user.  Then again, I've developed a flight rig with only one rack unit in it  but has a high voltage preamp pedal at the heart  :whoohoo!:

As for the Furman.  I'd replace that one cap, may be a few other bits here and there and no doubt it will take me a while to get the time to do it.  But it sounds/seems possible that there are other parts in there that have A) taken some beating or B) could possibly be screwed already.  So Rusty I may take you up on your offer.  I will perhaps get to checking the components out to see where we are first of all though so we will take it from there.  It's nice to have a challenge but can be really time consuming what with all the other shit I got going on (and plus I'm lazy too  ) .

Ok guy's so here is the next question, what do you think caused this?  I thought these furman PC's were meant to indestructible??  I can definitely tell you I was not the one messing about inside with the unit.  It's stayed in my rack since I bought it of ebay a few years back and powered everything nicely.  Until a few weeks ago.

Again thanks to both you guys.

Resurrecting this thread despite the unit seemingly working now I replaced the brown cap.  I'm going to replace those black Panasonic caps.

How can I clean off the black tar like substance that is on the PCB's?  I will re-cap this unit and sell it I think.

Hey RG, you can buy PCB cleaning stuff (spray?).  Not sure what a good brand is for that.

I dunno, I thought most people used alcohol the isopropyl stuff.  I dunno if that is going to shift the black tar like substance.  I could try it.

CRC makes a ton of electrical sprays , cleaners etc. It's all over the states but try amazon I have gotten it from amazon before.

[rabidgerry]

I will have a look.  Also see them on amazon too  Thanks for that.

CRC also sells under the "kontakt chemie" brand name in Europe.

I've been reading through this thread, and looking at the pictures, I noticed something, and I wonder if it offers any explanation to the cause...

Am I the only one who thinks the screw heads that hold the PCB's to the chassis, have rust on them?

Has this Furman been stored, or used in an excessively damp environment?  Furman's ARE bullet proof, but they are not waterproof. No electronics likes moisture in it's circuits.

Just an observation.

My old house was quite cold but I wouldn't have said that room it was in was damp or anything, nothing else was affected in the slightest so I'm ruling that out.  However the previous owner might have stored it somewhere.

I think the outcome of this was when I finally got caps for it it worked fine.  However I have other caps that I bought that I still need to replace.  Panasonic ones which can be seen in some of the pics.

Hey Gerry,

   Have you looked at Mouser Electronics? I believe they ship world wide.
