Is it normal for the LM317 in the tape speed mod to get fairly hot? Through some uneducated experimentation using your diagrams and Chris Skinner's additional notes, I wired the 3rd pot lug in your diagram (the unused one on your 5k pot, although I used a 1k pot) to the "in" leg of the LM317 to get chipmunk style high tape speeds at one end of the pot turn and very low near stop speed at the other. I also changed the resistor to a 47R. All works well except that the LM317 does quickly get hot, although it's not too hot to touch. Is this normal or have I messed up?
