- GovPlanet / IronPlanet: Military and municipal surplus auctions frequently list "Portable Transformer-Power Distribution, McGraw-Edison."
- Craigslist & FB Marketplace: Search under "industrial transformer," "portable substation," or "temporary power panel." The sellers often don't know the model number, so look for the distinctive rectangular enclosure with multiple Cam-Lok outlets.
- Scrap Yards: Tragically, many W9s have been scrapped for copper. If you have a good relationship with a local scrap dealer, ask them to alert you when an old industrial power unit comes in. You can often buy it for just above scrap value.
- Dedicated Forums: The SmokStak forum (antique engines and machinery) and Mike Holt’s Electrical Forum have classified sections where W9 units pop up for sale.
- Will survive being dragged across a rocky hillside,
- Can be repaired with basic hand tools,
- And still functions after sitting in a barn for fifteen years,
The typewriter had an appetite for stories about unnoticed people. Lena wrote about the night janitor who hummed old jazz into empty lecture halls; about a commuter who memorized bus schedules like prayers; about the barista who painted names on lattes with a trembling hand.

- Add GFCI Protection: Original units lack ground-fault protection. Install spa-rated GFCI breakers or external "spider boxes" with GFCI protection for all 120V receptacles.
- Install a Digital Metering Panel: Replace the old analog voltmeters and ammeters (if any) with a digital multifunction meter from Yokogawa or DROK. This allows you to monitor real-time kW, power factor, and frequency.
- Retrofit LED Lighting: Many W9s had an internal incandescent lamp for nighttime service. Swap this for an LED equivalent.
- Grounding Upgrades: Ensure the grounding lug accepts #2 AWG copper or larger. Modern NEC code requires a driven ground rod at the point of use.
- Paint & Corrosion Protection: Sandblast the enclosure and apply a two-part epoxy primer followed by a high-visibility top coat (safety yellow or OSHA orange). This not only preserves the metal but makes the unit safer on dark job sites.
