I'm confused regarding the RK-4D32 tube. My Collins 32V manual's schematic has one pin-out, my 60's era ARRL Handbooks have a different pin out. The Collins schematic identifies the PA as a RK-4D32, the ARRL Handbooks' tube charts only have the 4D32 tube.
Can anyone clarify this, that is is a 4D32 the same tube as a RK-4D32 tube, and what is the correct pin out if the tubes are indeed identical?
Thanks Frank Lotito K3DZ
