Members rawk100 Posted May 6, 2008 Members Share Posted May 6, 2008 No, not that sort of date! My friends got a mustard coloured Distortion + with a block logo and he thinks its late 1970's but he's not sure. Is there any way of finding out exactly when it was made (like by any serial numbers, etc)? Thanks...... Quote Link to comment Share on other sites More sharing options...
Members Turd Furgison Posted May 6, 2008 Members Share Posted May 6, 2008 the code on the back of the pots will give you the approximate date. Quote Link to comment Share on other sites More sharing options...
Members rawk100 Posted May 7, 2008 Author Members Share Posted May 7, 2008 Does a particular code related to a certain date or is the actually date stamped on the pots....? Quote Link to comment Share on other sites More sharing options...
Members bieke Posted May 7, 2008 Members Share Posted May 7, 2008 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 Quote Link to comment Share on other sites More sharing options...

Members rawk100 Posted May 8, 2008 Author Members Share Posted May 8, 2008 OK, the pedal is an early block logo with LED but the circuit board is covered with foam and I can't see the pots. There is a serial number where the battery goes and its 4-151304. Does anybody know what year this number relates to, maybe 1984?........
