Vintage electronics repair, restoration, troubleshooting and engineering—done at the component level.

XrayTonyB features in-depth repairs and restorations of vintage stereo receivers, amplifiers, radios, test equipment and other classic electronics. Videos focus on real troubleshooting techniques, circuit operation, measurements, component testing and the reasoning behind the repair—not just replacing parts until something works.

You'll also find custom electronics projects, modifications, test-equipment demonstrations and detailed technical experiments.

From classic Marantz, Pioneer, Sansui and other vintage hi-fi equipment to vacuum-tube electronics and unusual repair challenges, the goal is to understand how the equipment works, determine why it failed, and repair it properly.

Occasionally, I also cover specialized medical imaging equipment and related electronics.
