Midi Box 64 Power supply

Testing/Troubleshooting
1

Hello everybody!

I´ve read  “Core power supply theory of operation” and

so I understand the higher the voltage the higher the temperature.

But I´m no expert. Could you answer me whether a  12v PSU will produce to much heat in the 7505 regulator without extra heatsink?

Thank you in advance

Yes, 12v is too much :frowning:

Ok, I´ll get another PSU.  :-         

Thank you very much!
