It is probably not on the filter board unless the two boards are combined in the TS-530. I don't know for sure if the TS-520 manual is applicable. Although it shows the crystals and trimmers in a photo and on the circuit diagram, I couldn't find a procedure for their adjustment. It would help if you could find a copy of the TS-530 service manual. Fred K4DII |
