I plan to give one Breadbin the full delux spa treatment with new caps and heatsinks everywhere. I will also put a new cap in the one C64 power supply Ive found that can be repaired. The regulator 7812 in the power supply is attached to a huge heatsink so it should be ok but its more than 30 years old so a new one might be good especially as I can get to it.
Something I belatedly realized.. The 1541-II disc drives have a very similar power supply that is also usually sealed and could also be now putting too much voltage into your disc drive. Those who use those SD card replacements no worries for you. But if youre like me and you like using a real drive check that power supply too. On the large original drives the power supply is INSIDE the drive. I am going to try to look inside the one i have at some point and see what voltage its feeding out.
All power supplies should be checked really at this point. So your Vic 20 , c16, plus 4 etc. Be careful with mains voltages.
Thanks, i look forward to testing it
Yes your right about the 1541-II drives, they did have similar issues with their power supplies.
Would be great if someone could produce a replica C64 power brick one day, that would be the ultimate replacement!
