Hi I was wondering if there is any suitable regulated/filtered DC supply's for running 4 volt battery-valve filaments with high amperage for a 6+ valve set.

Also is there any pre-designed ABC+ supply schematics? etc 90v.

This isn't exactly for me, it's for my father's brother who likes to dabble in the 1930's valves... and is having trouble ither making up one for himself or finding one suitable which is fully filtered.😉

Cheers.
