BULLETIN # 13
MODEL: TS-820
SUBJECT: RIT MODIFICATION

                                                           
   We have had a few reports of the TS-820 RIT tuning being
   "rubbery". The following information will solve this.
   
   HOW TO MODIFY
   
   1. Remove resistor R27 (lK ohm) on AF-AVR UNIT (X49-1080-00).
   
   2. Install a 10K ohm resistor on foil side of AF-AVR UNIT
        --- see Figure 1.
        
   3. Install a lKohm resistor on RIT control --- see Figure 2.
   
   4. Install a capacitor (3.3uF - 10uF) between RIT control and
      ground --- see Figure 2.
        
   5. Adjust VR-2 on AF-AVR UNIT (X49-1080-00) for the same
      frequency as the center position of the RIT control.
