All you will get with different rectifier tubes is a different voltage drop of the B+ voltage. And a corresponding change in voltages throughout the circuit. Use the rectifier that the circuit was designed with! A rectifier tube is NOT part of the music signal!
Preamp Rectifier Tube Confusion
I have a Primaluna Prologue 3 which uses 5AR4 rectifier tubes which id like to roll. I’m looking at ShuGuang WE274B tubes which list as replacements for 5AR4 / 5U4G / 274B.
However, the Primaluna manual lists compatible tubes as: GZ34, CV1377, 5V4G, 5T4, 5Y3 and Upscale Audio also list the Philips 5R4GYS.
Any idea if the ShuGuang would work?
