Definitely use the type of heat sink compound called heat sink compound. Live large. Go the Full Monty. Buy two tubes.
What heat sink compound to use in a Musical Fidelity A1?
I'm doing some (hopefully) minor repairs on a 2008 Musical Fidelity A1. Removing the top cover reveals a 2" x 10" block thermally connected to the cover plate with white-silicon-grease-looking heatsink compound. There's quite a lot of it there, and I will need to clean it off and replace it before putting the cover back on.
What kind of heat sink compound should I use? My searches mostly turn up tiny tubes of compound to be used on CPU heatsinks. Or I see industrial materials. Any specific suggestions on what I should use? How much do you think I'll need for a very thin coat over that big of an area?

Use a small blob of goop at one end and spread it thin with the plastic barrel of a Q-tip. You will need a lot less than you think. The thinner the application the better the heat transfer. |
I know it has been a couple years, but I am also concerned about heatsink for my A1-2008. How did your work go on your A1? Any advice you can give about refreshing the heatsink compound or other work on the A1-2008? It is an absolutely amazing sounding amp, in a number of ways beats my OTL tube amp! |
