Assuming you're serious (I can't tell whether you're kidding or not!), please take care. Look for signs of damage or burning and be prepared to replace components affected.

Be aware that there's a more than even chance that some capacitors, especially electrolytics, will not perform well. Some resistors can also have drifted out of spec. Electromechanical contacs (switchs, plugs and sockets, tube holders) may need cleaning. Transformer windings should be checked for continuity.

I'm sure other people can suggest plenty more cautions before assuming that it will work.
