Hello , Can someone tell me what Voltage power transformer I need for this
regulated psu? Its for a 6sn7 preamp and the total current draw will be about 10ma. The choke will be 10h 400ohm and the output should be about 201v
the zeners are 110v each.
Would a 250-0-250v @500ma work? not sure how much headroom I have to have ,I also have a 350-0-350 @100ma
how do you know what the upper limit of input voltage is for the regulator
thanks
