SB-872 TS-930S CW Pitch Tone Shift 7-06-83 Some users of the TS-930S have reported a slight change in the CW pitch tone when the MONI switch is turned ON and OFF. This may be corrected by changing the following components: On the Signal unit (X57-1000-XX) change R826 from a 1 K ohm resistor to a 10 K ohm resistor and remove C601, a .022uF capacitor from the foil side of the circuit board. Notes: This change is applicable to units before serial number 3070221 only. Time required for this change is 1/2 hour. CLM (c) 121589TKC
