The schematic seems to be revised; compare to the version shown in the BAF-2022 video. The biggest surprise, to me anyway, is the disappearance of PNP's emitter resistor. In Nelson's article "DIY Opamps" on his PassDIY site (link), his opamp circuits that used a PNP for the second gain stage, did have a 10 ohm emitter resistor like the one shown in the BAF-2022 video. But now, poof, gone.
