RE: Is this feasible? Rectifying 6.3v for heaters

Phil - The cap. wouldn't have to be so big. Using the Morgan Jones formula for determining a cap. value, C uf = Il/delta Vp-p x 6000uF.
You have to pick a ripple value in Peak-Peak voltage. Let's say you can tolerate 10% ripple or 0.63vpp. Then C uF= 0.6A/0.63Vx6000uF= 5714 uF. I would bump it up to 6800uF. Is that too big?
