    0-30V Stabilized Power Supply

    How i have to connect it ? how its right ? how i can get +-30V ? This ?                                           OR              This? _Supply1_              _Supply2_                 _Supply1_             _Supply2_               |               |          |               |            |      ...

    0-30V Stabilized Power Supply

    now i am confused: i will build the supply 1. I have an 24V Transformer witht 8,33A 2. I have the PCB(done) with the old circuit 3. I have to change parts in the circuit 4. I would use the TL081, BD140 in the old circuit 5. I take two 4700

    0-30V Stabilized Power Supply

    ok i hope i can find the MC34071 OPAMP i will use max  30V@2A how much Volt i can get with a 24V Transformer ? i change the OPAMP to MC34071 if i can find it. an change the 2n2219 to BD139 on a heatsink I build 4 Supplys in a Box i can put all the BD139 on a Heatsink will it work fine...
