Opened up an Orion 2500 the other day, theres like a white goop in it. Ive seen this before in a sony amp. What is it, and what purpose does it serve?

Ill try to get some pics to show what I mean.

did you happen to notice how it is magically strategically placed around components?

that means it's extra donut jelly from the office that morning... go ahead, eat it.

I figure its some sort of glue, but its not dry, just wondering if thats normal.

If it's around the mosfets and whatnot, it's there to aid in heat transfer and such.

So its alright that its not dry? Nothing to worry about?

its not glue - it's more like thermal paste...

e.g.- http://www.newegg.com/Product/Product.asp?Item=N82E16835100007

it will never be dry. it's supposed to be there. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

I'm gonna use Arctic Silver on my Brutus whenever the GF gets around to resoldering it; Awesome heat interface; Super-tiny particles of silver in oil. Way more effective than the tape or paste.

Nothing to worry about. It's good that it's there. It's a thermal compound as Nick pointed out.....to aid the output transistors in dissipating heat to the heatsink.

AS is good stuff. most recently i used it in a system build over the summer, OC'd the hell out of a prescott - runs ~45C* under load //content.invisioncic.com/y282845/emoticons/eek.gif.771b7a90cf45cabdc554ff1121c21c4a.gif

x2.

I'd watch where your amp has been, I don't think it's been 100% truthful with you...

IIRC, Dave Navone said it's there to prevent induced noise. An insulator.

I had some time alone with the amp , sorry man ;[

Was kinda hoping you wouldnt look inside
