I am trying to restore this old Electro-Matic rectifier. It is rated for 250w at 120/240 VAC input and 120/240 VDC output. It contains a multi tapped transformer, two fuse blocks, and two selenium bridge rectifiers. I am intending on cleaning and repainting the unit, replacing the selenium rectifiers with modern silicon ones, and adding some flickering blue/purple/green leds to give it the mercury arc rectifier look. The old selenium rectifiers will be stripped and repainted or clearcoated, and will be reinstalled for looks, just not wired in. The transformer is quite beefy for only being rated for 250w, and I'm thinking the ratings are reflective of the rectifiers themselves more than the transformer. Since I'm replacing the selenium rectifiers with silicon ones, I would like to take advantage of any extra headroom the transformer has, within safe limits of course. The only information on the transformer itself is the letter "R" on one side and the number "1221" on the other. I would guess it weighs about 20lbs. Also I have found no documentation online for this product whatsoever, and any additional information would be much appreciated. I will attach pictures of the unit.
