National 83 NOS Rectifier
[5U4]

National 83 NOS Rectifier
These appear to be relabeled National Union Rectifier tubes by Richardson Electronic who used the National Electronics name (confused yet?). These have the exact plate, mica spacers and getter structure as well advertised National Union 5UB4's. The 83 tubes rectifier do require a UX-4 sock though.
