Sounds like a brilliant archaeological dig, but don’t forget that a ‘70s MOSFET will probably choke on the 5G's 2.4GHz RF front‑end. I’ll pull out my vintage op‑amps, solder a 47k series resistor to the gate, and make sure the bias network looks symmetrical before we hand it to the market. Nostalgia’s great, but if we want to keep the phone alive, we gotta respect the physics and the schematic. We'll have to use a modern driver IC for the high‑speed I/O, but I’ll keep the MOSFET as a decorative relic on the board. Just don’t expect it to survive a single call.

Nice idea, but remember that a ‘70s MOSFET will probably bite the 5G signal like a dinosaur bites a smartphone—so I’ll keep it as a decorative relic and hand the heavy lifting to a modern driver IC, just like a museum curator keeps the artifact safe while the exhibition runs. And don’t forget to add a 47k resistor to the gate so it stays in line with the bias network, otherwise you’ll get more sparks than sales. Let's do the math, not just the hype.
