Triode
.25 Amps
The RCA 112-A / CX112-A Vacuum tube is a triode power tube. It requires a UX-Base four pin socket.
The 112-A / CX112-A is NOT the same as the CX112! The CX112 draws a .5 amp. The CX112-A draws a .25
amp. Now to make things more confusing, a 12-A is the same as a CX112 tube. It also draws a .5
amp. So a 12-A and CX112 are the same. A 112-A and CX112-A are the .25 amp version.
