Help with CTS Pot Code values / Schematic

[jjasilli]

Hi guys,


I need help to find the values of both pots on a vintage MXR Dyna Comp model 202 pedal.  The pots need replacement. 

1.  I can't find a schematic; anybody have one? 

2.  I can't decipher the pot codes:  i) 100-1230-101   1378318;  ii) 100-1230-102   1378334

Thanks!

so they don't ohm end-to end, or wiper to ends?

No, the pots are non-functional and won't take a meter reading.

Take a look at this:   https://www.electrosmash.com/mxr-dyna-comp-analysis  --  you might be able to compare your board to this model /clone, and get some ideas.  Not sayin' it will be the same, but I bet it's close.

acheld:  I'm seeing 50K log & 500k linear pots on the schematics I can find, which don't match my model #.  But this doesn't seem to jive with pot codes, whatever they do mean.

Jim Dunlop se t me the parts #'s and I can order them. They won't share the schematic which they consider to be proprietary.
