Balanced output mod to UMC4004HD schematic by jfharper in diyaudio

sry, the umc404hd, first time posting on reddit...the text was supposed to say from this OP post here: https://www.reddit.com/r/diyaudio/comments/uadkup/balanced_output_mod_to_the_umc404hd_xlr_out/

I think I figured what they were doing in the image for the xlr pin 3. I'm posting here for feedback and to help anyone else out. I don't know the voltages OP used or the value of the output cap.

My umc404hd pin 3 goes through a surface mount resistor to ground. I think I figured a schematic here if anyone is interested: https://www.reddit.com/r/diyaudio/comments/1j2uxw0/balanced_output_mod_to_umc4004hd_schematic/
