I have an old RMI 140 solid state amp with a broken pot (the shaft pulls out of the body).  I am trying to find a replacement  but the pot does not have typical marks such as  "A100K".  I tested the pot with a multimeter (dial set to  200k ohms) and got a reading of 101.1.  The only markings on the pot are  "CTS", "USA",  "204-1040",  and "1376927".  Can anyone help identify the value of this pot?  Thanks in advance for any help with this problem.
