Dating Eden amplifiers by serial number

“For US Made Eden amplifiers, the first four digits of your serial number represent the year and month (in that order) of manufacture. For example, an amplifier with the serial number0408A1234 was built in August, 2004. For pre-USM amps, they are simply coded with the date”
