No, that resistor and capacitor in the endcap is a AC coupler so that any D.C. Offset in the audio signal is blocked from the headphones - it saves battery draw and should be kept in circuit. I need to know about shield ground - it is the brown thing sticking up slightly in my photo. Probably goes to same place as the black wire but I'd like to know for sure. As I'm putting in a CTX audio jack it probably doesn't matter as you can't count on shielded lines on the phones themselves.

The copper wire goes to capacitor C64..front leg. Blue Box Res & Cap in the circuit, my opinion, not necessary . I think they were added around 1998/99. The copper ground wire was added to the Excalibur 2's.



Effort is Important, But knowing where to make an effort can make all the difference!
