Product information "Psvane 274B-T-MKII Psvane Reference Mark 2 T-series"
Rectifier tube: Psvane 274B-T2  Psvane Reference T-series Mark 2
 
274B is very close in all spec details to 5U4G, 5Z3P and even 5AR4/GZ34. The 274B requires a filament current of 2.5A  which is lower than the 5U4G/GB or 5Z4P which would need 3A.
A 5AR4/GZ34 requires 1.9A only. Since that difference is very small most good designed amplifier power supplies should easily accept this. To replace a 5AR4 or GZ34 please refer to your amps manual to make sure this minior increase in current can be tolerated by the amps power supply before (!) you use a 274B instead.
 
All Psvane tubes are selected to the highest grade and re-tested at Tube Amp Doctor in Germany.
Suggested burn-in time is 30-40 hours
