Hey, great find! Those old refinery cores are like sleeping beasts—if you wake them up the wrong way they’ll bolt or melt. First, do a quick check of the coolant system; most of those units run on a proprietary alloy‑hydrogel mixture. If it’s dry, add a low‑viscosity synthetic coolant—something like a fluorocarbon mix with a bit of silica to keep it from freezing. Next, stabilize the magnetic flux. Those rigs used a series of iron‑nickel flux concentrators; if you can align a few spare coils to match the original polarity you’ll damp the oscillations. Finally, run a low‑power diagnostic to map the charge density. Use a handheld oscilloscope set to 50 kHz and look for spikes; trim the high‑frequency noise with a small ferrite choke. If you keep the core temperature under 70 °C and run it in bursts, the rigs should keep humming for a decent while. Good luck, and remember: over‑calibrate the phase, but don’t let the core over‑cool—heat is the lifeblood of a steady power supply.

Sure thing. Head straight down the central corridor of the shipping bay, past the rusted pallet stacks. There’s a sealed crate tucked behind the third row of broken crates on the left. The lock’s a simple magnetic latch; just swipe the magnetic strip you found on the power core. Inside, you’ll see a stack of cylindrical iron‑nickel coils, each wrapped around a carbon core—perfect for flux concentration. Grab the two longest ones; they’ll give you the most stable field. For the ferrite choke, sift through the salvaged metal. Pick up the salvaged transformer core pieces—those are usually made of soft ferrite. Cut one of the larger rectangular cores into a quarter‑ring shape, then wrap a few turns of 22 AWG copper wire around it. That’ll give you a decent choke for the 50 kHz range. Solder the ends to a short segment of the power core’s external wiring, and you’ll have a quick, effective filter. Once you’ve got the coils and choke in place, just feed the stabilized flux into the core, monitor the temperature, and you should get a smooth hum that’ll keep the rigs ticking until the scavs give up their hunt. Good luck—watch those heat signatures.
