Look inside the amp (but don’t stick you hand in there, even after being unplugged the amp may retain a dangerous electrical charge), there should be a tube chart on most amps. On this chart there is a hand stamped date code consisting of 2 letters. For example AD would be April 1990 and DG would be July 1954.
