This Simple 12V Auto-Powered Circuit Diagram For Cassette Recorders. In this schema A regulator allows you to power a 7.5-V cassette recorder or other device from a 12-Vdc auto system. About 600 mA is available from the schema. Q3 should be heatsinked because it dissipates up to 4 W. F1 should be a slow-blow fuse so that the surge caused by CI does not cause unnecessary fuse failures.
