Keeping my devices in good shape
Hi,
A fellow told me that the belts of my C64 tape/disk drives and printers tend to "break" with time, unless taken care of. He suggested that I apply some silicone oil to the belts. Here's a picture of the stuff he recommends:
Do the belts really deteriorate over time? Is this a good idea at all? |

Ofcourse they decay, its a rubber mix.
lubing them with silicone is only a plus. |

ready.

best is to use 1541-ii with chinon direct drive mechanism, those are without belt.
Still good to know to use the silicon oil for the belts. |

I am wondering about another device. The 1571.
It is getting more and more "buzzing" from the "trafo".
I guess the capacitors needs to be replaiced with new.
Is the buzzing harming the diskdrive? (more and more ac and less and less dc)

If we're talking about decaying hardware in general: my 1571 produces interference, so badly that monitors that are close by start 'waving'.
Probably also a PSU problem... any ideas how to fix that? |

The el. caps may be dry over those years.Try to replace them or change with higher uF value.I have replaced the caps in my Ocenanic,there are two 100uF.When i measured them one has only half of the capacity and the second was in tolerance.But that seems to be normal for the 21 year old drive..:-) But depends on the capacitor manufacturer too.In CBM HW are better parts from those years than in todays PC crap HW especially caps in the PSU's and MB. |

Cosmos, after you had replaced the caps in your Ocenanic, did the interference disapeared?

There are certain devices for measuring.Some multimeters have capacity measiring,but they have a limited capacity.I have one,but this is limited to 22uF.Better device that I have is an ESR tester. |
