This video shows how to enhance a Sony XDR-F1 HD Radio for improved internal cooling and extended memory retention. These radios are among the best AM/FM tuners available, but they run HOT and benefit from improved internal cooling using a small fan. They also have very short memory retention during a power failure, so we can add a super cap to extend that to a few hours. Of course, please proceed at your own risk!
Parts List:
- 1.5F@ 5.5V super capacitor
- 47-ohm resistor
- 1N4001 or equiv diode
- 12 Fan (e.g. Noctua NF-A4x10FLX)
- Hookup wire
