I did a search for VEBO and only found one thread and it didnt tell me anything. If the max VEBO for a transistor is 5VDC and I bias it for a class ab amp so it is just off then the max is a hair over 4.3VDC that can still be applied to the base. Does that mean the ac voltage that can be applied to the base cant go over this voltage of 4.3V or am I missing something here? I will have an ac signal higher than that, and each stage will be higher than the last so do I need to have max VEBO higher than my ac signal? I am trying to learn how transistors work, and I am a novice so any help will be appreciated.
