Picked up a 19VLNP22 tube. According to the Precision website it is a CR 24 which is the same as the 6100 19VLUP22 tube.
However, I looked for the 19V100 markings on the tube but is not there. The only markings are - a square then three small vertical lines with a V above them then the letter T. So how can I tell if this a 90 or 100 degree tube?
