In 1966 Ampeg started stamping the serial number onto the back left hand side of the B-18 chrome chassis, which was shock-mounted onto the lid.

Other 1966 B-18 characteristics: White silkscreened graphics, two channels with guitar and bass input jacks on channel 1, black stove type knobs, three metal switches, two large black transformers, black tube cage protecting the tubes and capacitors, light up plexiglass logo (which could be personalized for an additional charge of 50 cents), fuse, two prong power cord, schematic, one leather handle on top, two chrome handles on sides, 4 pin XLR speaker cable and jack, 4 chrome lid latches, chrome script logo, Blue Check vinyl covering, silver grille cloth, 18 inch Cleveland speaker, baffling, matching dolly with wheels.

The second serial number system was implemented in January 1965 and used until the end of 1969. These are 6-digit numbers which appear to have been applied sequentially, but are not date encoded. 1966 serial numbers ranged from 020000 to 049000. For more precise dating cross reference the serial number with the amplifier's transformer, potentiometer, capacitor, speaker codes and covering.
