I have a guitar amplifier (tube) that has a 7815 regulator that’s supposedly getting too hot, (according to other users). The solution is to put a heat sink on it I read. However after getting into it I find the part has an “isolated tab”. I had to make a very small sink to fit in the tiny space but not sure how to mount it, since it looks to me like both sides are a plastic-like material. Which side does it mount? Does it need a thermal paste?
Thanks
