Hi everyone - I was taking apart my 9090 heat sink to replace two blown output 2SC1116A transistors. I am a resourceful newbie when it comes to electronics and I manage most of the 9090 bring back to life stuff based on the forums, the service manual, some basic tools and meters I got since high school. Occasionally, I run into mysteries such as this:
What is the white stuff smeared all over the heat sink and on the transistors bottom. My guess would be this is some heat resistant insulator paste but I have no idea what it's called, where to get it and how to apply it? It seems to me it should not get on the transistors legs - but it did. Can anyone hand me a pointer? Thanks.
