1. Remove yellow 2200K cap of oscillator board from the  10-ohm resistor
2. Remove 33-ohm resistor of oscillator board from RF choke
3. Remove orange or green wire of oscillator board and attached 33pf cap
4. Solder the leg of the 15 or 18-pf cap to input trace on PCB
5. Remove black wire of oscillator board from keying jack
6. Remove oscillator board
7. Locate jumper wire attached to backside of red switch
8. Unsolder the ground end of jumper wire closest to the relay
9. Solder this end to bare lead of 10-ohm resistor behind red switch
10. Remove 10-ohm resistor piggy-backed to 15K resistor located next to
the white sand block resistor and RF choke
