- Notes
- The circuit can be built using AC/DC power supply in which case it uses 25L6 as output tube and 25Y5 as rectifier, or using AC transformer in which case it uses 6V6 as output tube and 5Y3 or 5Y4 as a rectifier. The power output reaches 4W when using AC transformer. Schematic and parts list shows both options.
