gib71lpc Posted December 20, 2019 Share Posted December 20, 2019 I have a 1973 LPC which I bought new in early 1974. All original parts, wiring, pots, etc. The pot code is 1377348. The pots also have an additional stamped code - 70-028. Anybody have a clue what this code means? Contacted CTS but no reply yet. Thanks.

badbluesplayer Posted December 21, 2019 Share Posted December 21, 2019 The pot code 1377348 - the 137 is the manufacturer code for CTS, the 7348 means it was produced during the 48th week of '73 (1973). Quote Link to comment Share on other sites More sharing options...
gib71lpc Posted December 21, 2019 Author Share Posted December 21, 2019 Thanks. I already knew the CTS pot code. It's the 70-028 code I am looking to learn about. Quote Link to comment Share on other sites More sharing options...
gib71lpc Posted December 22, 2019 Author Share Posted December 22, 2019 Stumbled upon an answer thanks to Vintage Guitar and Bass. Pointed me to a Les Paul schematic and a note written in that schematic that #70-028 is a Gibson part # and that it is a 300K pot. Other reference links says it is a linear taper but I have not verified this yet... Quote Link to comment Share on other sites More sharing options...
badbluesplayer Posted December 24, 2019 Share Posted December 24, 2019 Doh! Yeah, that's the part number. Quote Link to comment Share on other sites More sharing options...
