LTSpice - Tip when simulating circuits

From a channel Lumen includes in full: Every sampled transcript is a hands-on or whiteboard engineering lesson covering impedance matching, push-pull amplifier classes, PLL samplers, slew-rate measurement and spectrum-analyzer troubleshooting, all taught with bench instruments. Titles are descriptive technical topics; the few mild hooks ('Why This BLE Device Drew 4×…', 'check if an op amp is fake') are fully backed by substantive teaching in the transcripts. There is no entertainment, review or promotional framing; the channel is a single engineer teaching analog and RF design.
