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

[WESTLOWER]

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.

David works on all amps not just valves

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

The 'goo' can damage the circuit board so it's not really a good idea to leave it. I'd mop it up off your furniture too, if I were you.

Glad somebody said that. I was going to mention it. The amp really needs immediate attention, as the leaking electrolyte may cause damage and could even be toxic.

If its under warranty is needs to go back to where it came from, not be repaired by an unrelated service source.

As other here have said, power supply caps without a doubt, had a few bits of original McIntosh equipment on the bench recently, and a few of the caps in one were showings signs of having leaked, just ask who ever does the work on it to change all of the large Electrolytics in there, they will all be of the same age, and thus all have the potential to go bad in a similar way.
Hope you get it sorted.

I suspect it is a lot more than 2 years old. If it isn't then it's a bit poor that the caps are leaking already.
