Raplacing the voltage regulators in the Commodore VC 1541 disk drive.

In a previous video I talk about my switch mode voltage regulator in a Commodore VC 20 or VIC20. Today I want to show you, if it’s make sense to also change the two voltage regulators in the Commodore VC 1541 disc drive. And guess what.... No more head problems with my switch mode voltage regulator design. Here we are replacing the old TO-3 packaged LM340KC for the 12 volt line and the UA7805KC for the 5 volt line. Both regulators are capable to carry 3 amps continuously! Have fun with my video and don’t forget to subscribe :-)

The switch-mode regulators are open hardware now! You can dowload the gerber files from Github: https://github.com/DigitalArtDeco/SwitchModePSUinTO3
