Peavey is the maker here whose serial rule comes from its own manual: a two-character prefix whose first digit is the last digit of the calendar year and whose second character is the product type. Because the decade is encoded by the length of the number rather than by the digit, one prefix yields two or three candidate years. Peavey publishes no range tables, and its online lookup is a server-side tool that covers only part of the formats.
Hartley Peavey built the company up in Meridian, Mississippi, through the 1960s and 1970s on transistor and hybrid designs. Serial numbers from that first decade are not documented as a series, so component codes carry those amps.
From late 1975 the two-character prefix states the last digit of the year and the product type: A for amplifiers and E for cases. The owner's manual examples are 5A-12345 = 1975, 7A-123456 = 1977 and 6A-12345678 = 1986, so the number of following digits gives the decade.
The 5150 heads and combos run 1995–2004 and the 6505 line takes over from 2005. By then the printed manual no longer carries a dating rule: the current route is the maker's online lookup.
Serials beginning 00- mean 1990 or later, and the prefix system itself was dropped after 1989.
20 Peavey models are catalogued with their production years, specs and safety notes.

Because one digit cannot name a decade, the count of digits after the prefix decides: five or six digits reads as the 1970s and eight digits as the 1980s.
Serials beginning with 00- are 1990 or later, and the prefix system was dropped after 1989.
Yes, on its own site, and the documented coverage is limited rather than complete.
