Allesandro

"Since 1995.  Earliest amps had no SN. 1996- 1998 had SN above AC connector. 1998 - present has SN under left hold down chassis bracket on back part of chassis.

All amps have specs and build completion date on inside cover plate of chassis." [Source: Hounddogcorp, Allesandro Amps, email 19/3/2008]

Ampeg

In 1946, Everette Hull established a partnership with Stanley Michaels under the name "Michaels-Hull Electronic Labs" to produce a new microphone pickup that Hull designed. The pickup was fitted on the end of an upright bass and was dubbed the Amplified Peg or "Ampeg" for short.  In 1949, Hull became the sole proprietor and changed the name of the company to the Ampeg Bassamp Company. In 1986, St. Louis Music, Inc purchased Ampeg. [Source: Ampeg ]
