My neighbor asked me to take a look at his non working Kenwood VR-506 AVR. So the first thing I did was to remove the top cover for a look and see. There are several radial caps mounted flush to the board. These caps have a rubbery semi clear substance at their base. Question to you who are more knowledgeable in such things. Could this substance be a sealant applied at the factory. The caps are not swollen or leaking from the top or sides. Is what I see leakage?
Are STK IC's difficult to replace?

Marvin

Update:
The STK IC arrived today and I got to work. I had already disassembled the receiver yesterday and created photos to guide me back if needed. Practiced my desoldering and soldering technique removing and installing the STK. Reassembled everything. Powered it up. It stayed powered up. He was happy. I was and still am happy. Now maybe he won't complain the next time I play my CD of "The Pipes and Drums of Scotland" at volume.
Many thanks to you for your input and info. This was a very gratifying, edifying and fun project.

Marvin
Could you use the same compound I put between my CPU and heatsink?
I still have some Arctic Silver.....a couple revs ago, but worked fine.
Too much is never enough
Just came from Fry's were I bought some Antec thermal grease.
Yes, that will work fine.

It's probably RTV type sealant, they must have had caps falling off in shipping. At least that is the only reason the company I work for does anything like that.
Leakage would be a sticky goo, probably full of dust depending on the environment.
The big old STK power packs are a piece of cake, usually just one row of pins to de-solder. The hardest part is finding them these days.
Thank you gents. I believe you are correct. That stuff is only on the larger caps. Makes sense to stabilize them. Now I get to dismantle this thing and wait for the replacement STK Another learning experience.
Don't forget the thermal compound.
Thank you. I did forget. Next stop, thermal compound store.
