Hey there,

I recently picked up a nearly-mint C64C with the original Datasette. After taking it home I discovered the Datasette wasn't working. Taking it apart and cleaning out everything I could, it still didn't work, so I did some poking with my multimeter and discovered the problem - the power brick is damaged somehow and it provides just enough juice for the computer to boot up and display graphics, but it's too little to power the SID chip and the datasette.

Did anyone here ever have the same problem? How would I go about fixing up the power supply?

Thanks in advance.

Best advice I can give, is use a C128 power supply.

They are far more reliable, more modern tech, and much better than C64 power bricks (which I wouldn't even go near - sudden C64 death is always a risk with them).

You need to change the plug on the PSU, but it's not hard if you follow the pinouts.

C128 PSU Pinout

Edit: another bit of advice I'd say is don't use that PSU ever again!
