Part 5/7:
The variations in part numbers and ratings suggest that these components, although similar, are not identical. The speaker hypothesizes that using different types of germanium diodes—some with 25V PV and others with 65V PV ratings—could influence circuit behavior and voltage output. Since all components are stored together, the possibility exists that some circuits were assembled with one diode type, while others used the different variant, contributing to the voltage discrepancies.
