Sounds like the old GPO/BT trick of sending somebody down to the stores to get an A.C. battery, or a can of tartan paint! Or how about a non-inductive choke?
I still take great pleasure in working with the older tube gear ("valve" in Brit parlance). I still regularly use an amplifier my father built in the early 1960s with the ubiquitous twin 6V6 output tubes in push-pull.
Operated on 100-500 volts, or more.
Sometimes quite a lot more! 807's in a typical R.F. final come to mind.
