Hot radio stack
Hi Guys, just wondering what might be causing a radio stack to feel hot?
Specifically, I am flying a 1974 pa-32 300hp with king KR 85 TSO ADF and KX175B TSO. The nav/comm is warm, not too bad but the ADF is almost too hot to touch. I have all selectors switched to off. This makes no difference to the heat. Switching avionics off cools the nav comm but the adf remains hot.
Any help would be appreciated!

Thanks
