A request was made for a 1.2 volt amp. The idea was to make a radio powered by a single rechargeable cell. My last three post were in response to that question. Tonight I will present a the amp with different supplies to see how it would work at higher voltage levels.
With the same circuit there is quite a change in output when the supply is varied.
The goal of a 1.2 volt supply radio is possible but it would be a lot easier to use 1.5 volt or more.
