George, I was actually going to make them heavier than that. The screen windings were going to be rated at 250 mA, the bias at 125 mA, the 12 V at 2 amperes, and the 6 V winding at 10 amperes. Most all the supplies will have losses and actually require more current than the DC output. These will be able to run full wave, half wave, and doubler circuits with room to spare, running at CCS. I wanted to do this to keep the heat way down to where they could be mounted in chassis that wasn't ventilated well. I figured a rough price of $100.64 each with a watt rating of 205 watts to compare to Dahls pricing of similar. These use an EI 1-5/8" laminate 1-1/2" in depth. The physical size of the core is 5-1/4" wide x 4-3/8" high x 1-1/2" deep, with the steel weighing 8 pounds. The estimated finished weight will be about 12 pounds. You can look up a similar transformer at Dahls website weighing 12 pounds and 205 watts. Thanks for the interest, I should be up and running around December.
