POWER SUPPLY CIRCUITRY
I HIGHLY RECOMMEND THESE POWER SUPPLIES

||||||||||||
These items are available directly from the sources listed within the table. NOTE - I do not stock these items as the cost to bring them in and then turn around to ship to you would be crazy, so I list these as a convenience so you don't have to drive yourself nuts searching around the web to find them. The sites I have listed below may change product offerings from time to time. I don't follow up regularly so if you find the links are a dead end or if the pricing has changed please let me know so I can keep this page current.
WARNING Be careful when selecting power supplies. If they're not type approved and they cause injury, fire, or death your house insurance will likely tell you to take a hike when you put in a claim. Check with your insurance company and know the rules! All selections I recommend are type approved and carry UL and/or CSA and/or NRTL safety approval. They might cost a buck or two more than some of the stuff you can find on various internet sites, but you can sleep well knowing they're safe to use.
