I have a salvaged power transformer from an Uninterruptible Power Supply that I've been saving for years, hoping to find a good use for it. Well, I think I may have one. I'm restoring an old RCA 810K1 floor radio, and I need to buck my 124VAC line voltage down by about 12 volts. I'm sure most folks here are familiar with the notion of wiring a 2-3amp low voltage transformer so as to buck or reduce line voltage. What I'm uncertain of, is whether my choice of this transformer is a prudent one. Data for these Lei built transformers doesn't seem to be widely available, but it appears to be a standard 120V to 12V, center-tapped step down transformer. Now, I know these are used reversed in the UPS, so a low voltage, high current can be stepped up to a lower current, 120VAC to power the peripherals.
My question is whether or not such a transformer can be used with 120VAC as a bucking transformer? Power draw by the radio would be probably around 100 watts at 112VAC. I know I could buy a filament transformer for about $20 to do this, but I'd much rather do this for free with my existing transformer. Any thoughts are greatly appreciated!
