To determine the date of manufacture of your Pioneer component, look at the serial number. The first two characters will give you the year and month of manufacture. The first letter is the year, the second letter is the month. For example, taking into consideration the age of the equipment:
ZA would be 1979, January
YL would be 1978, December
KK would be 1964, November
Not all Pioneer components followed this rule. For example, the Pioneer SE-700 headphones had a two letter prefix, but did not follow the table above. For these components, it is rumored they were made by another company, possibly Azden or Stax, for Pioneer.
But, generally speaking, most all of Pioneer's components from 1954 followed this table.
