Can anyone recommend a better rectifier tube?


I have replaced the 5R4 rectifier tubes in my Jadis SE-300B amps twice in the past year. In February I installed JAN CETRON NOS 5R4WGB tubes purchased from TubeDepot. The amps have been used sparingly since then yet the tubes are now weak. This was the case with a previous set of theses tubes. Since installing these tubes I have been running the Royal Princess™ 300B tubes. Prior to that I used Western Electric 300Bs (manufactured about 10 years ago). Can anyone recommend a better brand or type of rectifier tube for this amp? Thank you.

I'm trying to persuade Sophia Electric to make a 5AR4/GZ34 rectifier tube that would replace the Mullard NOS in my Modwright LS100.

Just to be on the safe side, don't try a 5AR4 in an amp that calls for a 5R4. The 5R4 can handle more voltage, so stay with the one the manufacturer of the amp recommends.
