I have a Philips CD960 CD player which has been in storage for a while (okay, eight years). The rubber belts in the transport have hardened and stretched and need to be replaced. Does anyone know of a source for these parts? Philips service here in the U.S. doesn't seem to even know that such a piece of equipment ever existed. Any help appreciated!

If the belt is round or square, it can be replaced with a rubber O-ring. Take the old one with you and get something about 10-20% smaller in circumference. When I was doing AV repairs years ago, we'd get most of our round "belts" as o-rings for diesel engines from the Caterpillar dealer down the road. They were about half the price of belts from PRB.
Flat belts however are best done thru PRB.
An old Hitachi electric drill as part of a set with many attachments had a wrongly wired plug.
This is in New Zealand where the phase is the slanting pin socket on the left. The sealed Hitachi plug attached to this faulty drill had the red wire connected to the right hand pin as it is pushed in.
(Fault was less than tight brush scews)
As far as I've always understood it, 'polarity' on two-wire double insulated equipment, is more a matter of convention than safety, from a punter point of view. Not quite the same for the service engineer who has to get inside the equipment, where he will quite reasonably expect any power line fuses, or single pole switches, to be in the live (phase) wire, rather than the neutral.
There may be other issues - all my electrical theory was learnt at college a long time ago, and by experience over the years - but I don't think that there is a lot of (electrically practical) difference between a drill motor, a light bulb, and a piece of kit with a transformer based power supply.
Inexcusable really of the manufacturer to wire it wrongly, but I have seen many times, the two pin non-polarised europlug (thinking about it, there you go - two pin, non-polarised) fitted to Aiwa hifis, inserted theoretically backwards into the UK 13A permanent adaptor head, that they fit before shipping the item out to the UK, so clearly, they don't think it's an issue.

Reversing line and neutral won't stop a drill working.

That's good, thanks for telling the whole world.
No, but it will make Brian post to SER about it. That's a powerful effect in its own!
And all (AFAIK) recent power tools, especially drills have double insulation.

I'm seeing a lot of this kind of PSU wiring in DVD players these days:
One 2-pin plug connects to the mains, the other to a single pole power switch. By interchanging the plugs you can either switch and fuse the active lead, or switch and fuse the neutral lead. If you switch the active lead, then the case potential drops to 0V. If you switch the neutral, then the RF suppression caps elevate the case to full mains potential, albeit harmlessly. However, the resultant tingle can cause some consternation among consumers, and consequently some PR problems for manufacturers.

For Class II (double insulated) it should not be.

As I said I believed to be the case, also. But with the reservations regarding engineer safety, when the covers are off ( although it should be on a bench isolation transformer for open-case work, of course ... )
