Locate transistor Q37 on the board (toward the back right hand side.) The two capacitors are mounted on the foil side of the board underneath Q37.Locate the Control board on the bottom of the transceiver.Remove the top and bottom covers (16 screws).

Disconnect the power cord and antenna from the transceiver.

The recommended replacement value for each capacitor is 0.0022 uF, 50v (CK45B1H222K). The level may be increased by changing the value of capacitors C182 and C183 in the ALC circuit on the Control board. TS-940S's in the serial number range of 601XXXX through 708XXXX may be limited n SSB peak power as compared to full CW output.
