  • Notes
  • Model RA-100A was the first model of NEC radio. This first model RA-100A used a transformer-less circuit. The line up of tubes were 6A7-6F7-6B7-43-25Z5-B300B (ballast lamp). Considering power line stability and parts supply, this model probably ended up as being a prototyxpe only. See the follower, RA-100B. Just to be complete as a reference work we keep this model - even if it will not be found in a collection. We do list the ballast tube B300B but we do not count ballast tubes for the number of tubes.
