The following information gives valve line-ups for radios in use during WWII. Sets were mainly superhets and mostly mains powered, either AC or Universal AC/DC.Each section gives the type of set, whether AC mains (AC), Universal (U) or Battery (B).The position or inclusion of the " / " sign in the type codes of valves is not always consistent in contemporary information and valves may be marked or referred to, for example as "AC/HL" or "ACHL". Both mean the same thing.There are lots of equivalent valves and sets may be found with different types that work just as well.Check equivalents to commonly used valves. |
