I have a couple of old Chicago Standard (Stancor) power transformers (PA-8421). While one secondary is rated at 6.3VAC, 2A, interestingly they rated the other secondary as : "125 Volts, 1/2 wave 50mA DC" (It's just a two wire 125 VAC secondary, not center tapped)
I've hooked that secondary up to a full wave diode bridge, yielding around 195 VDC with a 100 uF smoothing cap. My question is: how does the current rating change going to a full wave rectification versus the as-rated 1/2 wave? Wouldn't the transformer run cooler in full wave versus 1/2 wave? I'm just curious why they used the 1/2 wave rating method.
