I can NOT find it !!!!!!! I saw one of Mike's (mikesradiorepair) videos where he did a long talk on the isolation kits for replacing TO-220 pkg finals.
I know that there are two types (for the most part) those that have mica insulators and those that have these rubberized silicone pads. If I recall correctly... Mike seemed to really like the rubberized silicone but I just found some materials doing a Google search that seem to indicate that the rubberized pads alone have about TWICE the thermal conduction of mica with thermal paste. And THAT sent me running to one of my favorite places.... RIGHT HERE!!!!!!
What say you here about this subject? Do you tend to go for the mica/paste kits? Or is the rubberized silicone good enough?
AS always... thank you in advance for any discussion at all!

re-reading that ... it just didn't look right.
When I said that the rubberized silicone had twice the thermal conduction.. maybe I should have said HALF. What I saw essentially said that mica/paste had ONE capacity to dissipate heat...and the rubberized silicone was WORSE by a factor of two. The graph seemed to imply that the rubberized silicone could only conduct/sink temperature at HALF of the rate of mica/paste. Hope I am getting this across clearly.....
