from the Analogman site MXR used pots with EIA date codes on them. They usually start with 137 which is the manufacturer (137 = CTS), then the next digits are the year and week. For example, 137 7903 would be a CTS pot, made in the 3rd week of 1979. Sometimes there are only 6 digits, for example 304731 would be 304 (stackpole) 7=1947 or 1957, 31st week. Other manufacturer codes are : 106 : Allen Bradley 134 : Centralab 137 : CTS 140 : Clarostat 220 : Jensen (speakers) 304 : Stackpole 328 : Utah/Oxford speakers 381 : Bourns 465 : Oxford speakers 285 : Rola 391 : Altec-Lansing 649 : Electro-voice 1098 : Pyle 67 : Eminence
