Using transformers from electronics

If you have a lot of lights I would not bother with them. I use 300 watt 12 volt outdoor lighting transformers.

A rather hefty wallwart would be a 12V 1 Amp unit.  For LEDs that would be great, but for incandescents that isn't very many bulbs.  You probably want something that is at least 5 amps if you have lots of incandescent bulbs.

Shavers and small appliances don't take much power.  There should be a rating on the power supply - AC or DC, volts, amps or VA.

One often overlooked inexpensive power source is computer power supplies.  Many folks have old computers sitting around gathering dust.  Those supplies start at several hundred watts, and much of it is 12VDC, just right for lights.

I open my closet door and see five of them in a box from older computers.  There are a couple of aging computers that will never be used again as well.  Lots of power there.

Dead computer power supplies can yield a very nice enclosure for many projects.  I have my auxiliary transformer for accessories mounted in one of those.  (Maybe you can fit the core of the CW-80 into one after you smash the case.  BTW, I use a conventional straight-blade screw driver to remove the triangle screws.  The blade is .140 wide and fits nicely across one side of the triangle.)

Dale, I actually ground down an old Phillips driver to make myself a triangle driver, worked just fine.

I also did some grinding initially, but my point is that a standard straight-blade screwdriver from my tool kit did just as good a job without requiring any grinding.  For folks who just want to get the CW open, they don't need a special triangular tip.  My screwdriver fits snugly across one flat of the triangle and works great.  KISS
