Well the weather really poor here so stayed inside and played a bit with the Turtle.
Arrived looking like this.
Dis-assembled, wiring marked
Horrible hack repair job on the back of the original circuit board
Removing Silver Sabre circuit board to replace the non functioning one in the Silver Turtle
Added Ground plane plate, as there is no metal control box like the Silver Sabre.
Original Turtle pots and switches cleaned and reused. Removed Disc trimpot from Turtle and resoldered to the circuit board of the Silver Sabre. New battery wiring, instead of the single 9 volt battery, running two 9 volts as per Turtle for extra run time.
Headphone and search coil fitting holes were tapped to fit actual connect-disconnect removable connectors. No longer will be hardwired. Still have to wire the connectors and a number of other things before I can say the control box is complete.
More to post as I progress.
