Well I did a little cleaning on the set the other night. Most of the time after work I'm kinda bushed and crapout in the recliner. Took off the strip that has connections for the batteries and gave it a little scrub and add some white to the lettering to make it a bit more readable.
Today I got home early from work about 2pm. I was thinking my little Trirdyn need a power source. Am thinking of using batteries at some point but for testing and servicing I like an AC supply. You have to be concerned about the batteries going weak while you are working on it. Dug around and found a few of the basic parts. Two hours later I had this:

Still in the testing stages, it's making about 215vdc So I think I going to add a little series resistor to drop voltage down a bit. I only need 90v and 22v. I used a power resistor with a slider so I can pick off any voltage I need by just moving the slider. It's like a pot. Actually it has two sliders, very handy so I can pick off the 90 and the 22vdc. Still have to mount up a off/on switch an a terminal strip on the back for the wires to terminate to. Have to run to the store to get a few parts. When I get this done I can put power to the Crosley and is what's what.

ps Here's the Diagram for the Power Supply:

It's pretty basic!! PS. was on pain killers and drew the diodes backwards!!
