If you're worried about the chassis blowing HOTs I recommend you do a light bulb test before installing the HOT, i.e. you connect a 40-60W bulb to the pads where the HOT collector (center) and emitter (right) would go. If it lights up and voltage is correct (138VDC) then you know it won't blow the HOT.
Like this basically (this is a POLO 3 but the test works the same way):
And no, you don't need to put your hand on the anode cap.
