Tubes may get hot to the touch, but your finger oil will not cause the tube to break when heated up, nor will it affect tube life or sonics. An amplifier, electronic amplifier or (informally) amp is an electronic device that can increase the power of a signal (a time-varying voltage or current).It is a two-port electronic circuit that uses electric power from a power supply to increase the amplitude of a signal applied to its input terminals, producing a proportionally greater amplitude signal at its output. By hot I mean you can barely stand to keep your hand on the amplifier back plate for any length of time. Class A receivers such as this are designed to operate in a very inefficient portion of the amplifier performance curve, and then naturally generate lots of heat.
