I just wanted to thank everyone for taking the time to help and for providing so much great information. It was all very helpful and I am a lot more knowledgeable now about this thanks to you all.
I drove over to Radio Shack this morning looking to buy the needed parts with no expectation they would have all the parts. They were having a 25% off sale on all their electronic components. They had all the parts I needed. They also had a box of new unused power packs from various devices. I picked up 2 12vdc 300mA power supplies for $2 each. My negative ion generator arrived for Oatly yesterday. Some days are just flat out more fun than others!
Thanks,
Ed
