As per thread title: needed to power the filaments in a (formerly) battery-powered radio. The mains transformer that is available has a secondary winding of 6.3 v.a.c. centre-tapped @ 1.5 amps. The d.c. O/P needs to be reasonably regulated since it powers 4 valves with 2v filaments. I could easily sit down for a few hours and investigate a few ideas but since I don't believe in re-inventing the wheel, I thought I'd ask here first: to me, this need seems to be a fairly common requirement in the world of vintage radio.
Thanks for your thoughts & ideas.
