Hey guys. One query for you. I've never seen the component for the input and output on this schematic. What is the switch symbol on the INPUT and OUTPUT of this image? I'm -- using LTSpice and can't find that particular part anywhere.
More specifically, it's a TS jack. "TS" means Tip / Sleeve. It's a mono jack. TRS, by contrast, is Tip / Ring / Sleeve, a stereo jack, like for headphones.
