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
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...
