25V types--RCA vs. Sylvania.
I have a choice of 2 NOS 25VABP22s for my Heathkit GR-900 project. RCA or Sylvania. Any input as to which was a superior tube as far as life, phosphor quality, etc. The set originally came equipped with an RCA CRT, but a Sylvania HV rectifier tube!
Either of them less likely to cataract in the future? Neither show any at this point.
