With the cat door still open, my kitchen is cold and drafty. The solution is obvious: add a tube amplifier. Here on the kitchen island is my PrimaLuna integrated, back from service. Since I plan to sell it to a buddy, it’s staying in the box. First, though, I’ll run it for at least 72 hours to make sure it’s fixed. When we get our first snow that sticks, I can close and insulate the cat door. Until then, tube heat is an option.
