    5A Variable Linear Power Supply

    Could you tell me the minimum voltage you can get out of this? Im only getting a min of around 9v max 22v. To be clear I am using a TIP32C rather than the TIP42C since it is all I had. Is this effecting my results? Maybe I need to redo the circuitry on my bread board. I am also substituting some of the resistors for multiple smaller value ones. Ex: Instead of 500ohms Im using 200-200-100 to create one. Also on one of my tests my 500ohm potentiometer make alot of magic smoke. So I replaced it with a 200ohm resistor that for some reason didn't even get hot? To be fair some of my components are a bit off the required items but they aren't off by what I think is a significant margin. Any advice is greatly appreciated. Another thing that I should note is that I had no 8.2ohm resistor so inst...

Another thing that I should note is that I had no 8.2ohm resistor so instead I had a 10ohm.

    Also if you need pictures I will post some as soon as I can.
