# How were battery radios converted to run on electricity?

A historic radio power-conversion reference comparing ways to electrify a receiver. Old mains techniques are not modern electrical safety instructions.

What the unlock delivers: **the exact original article, issue, printed page number, and preserved source location**. This is a historical reference locator—not a newly tested technique, downloadable kit, or claim of exclusive rights to the source.
