    Default Eek!! Amp leaking oily stuff..?? What's going on??

    So, today I noticed my trusty SS McIntosh MA7000 became incontinent... eek...

    OK, well, I've never had any problem with it, use it everyday. It never runs hot to the touch (on the heatsinks) or ever seems to break a sweat. Today I was spring cleaning and carefully moved it off its shelf onto a plastic record box so I could clean the shelves. When I went to put it back I noticed a puddle of weird brown liquid had formed under it. Never seen that before. The shelf where it had been standing until today had so sign of fluid or leaks. The liquid is viscous to the touch and has the consistency of motor oil. (see pic)

    Looking through the grill I can see some signs of 'leakage' inside too... (see pic 2) strange thing is that the amp was not dropped or anything, and was (seemingly) working fine with no issues until today. What on earth could have caused this?

    Can someone tell me what the hell's going on?? I've never seen this from an amp before... or even heard of it happening. A classic car, yes, but an amp...??

    Amp is currently disconnected and will remain that way for the foreseeable future until I can get this sorted.

    Probably.

    Shouldn't be too hard to sort out.

    Almost certainly leaking capacitors I would have though.

    Easy enough to fix.

    As above. Or someone spilled something. Look at the big caps inside. Probably one of them burst a seal

    Oh my god! There's nothing wrong with the bidet is there?

This is the supreme test. It is the glory of Lincoln that, having almost absolute power, he never abused it, except on the side of mercy".

    “You see these dictators on their pedestals, surrounded by the bayonets of their soldiers and the truncheons of their police ... yet in their hearts there is unspoken fear. They are afraid of words and thoughts: words spoken abroad, thoughts stirring at home -- all the more powerful because forbidden -- terrify them. A little mouse of thought appears in the room, and even the mightiest potentates are thrown into panic.”

    No, nothing spilled. Definitely coming from inside the amp.

    Leaking capacitor? Well, at least it's good to hear from you gents that it's not too serious/ hard to fix.

    Anyone recommended in London area for such a repair? Or do I need to send it to Jordan Acoustics (UK McIntosh-approved service dept)?

    ou might slip, you might slide, you might
    Stumble and fall by the road side
    But don't you ever let nobody drag your spirit down
    Remember you're walking up to heaven

    Don't let nobody turn you around

    Learn from everyone, that's what life is for
    And don't you let nobody drag your spirit down

    Had some good work done by Jauncho (David) of this and other forums.

    Edit.

    Phil beat me to it. AD Audio is the company name David trades under.

    Yes I have spoken to David before - I have his number.

    I thought he only worked on valve amps? Well, I'll give him a call and ask. He's near me in SW19 so hopefully can help.
