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?

@jl1ny not to be a killjoy in your case - but if you are going to tube roll to better the sound of the your system, do it with input tubes - spending $ to roll rectifiers are barking up the wrong tree https://www.primaluna-usa.com/tube-rolling |
be careful applying these ’review results’ of rectifiers in little headphone amps to real amps driving real speakers with serious electrical loads as pointed out below, think about what a rectifier actually does in circuit ’after enough scotch, malt whiskey and/or 420, even the same sh*t will sound different’ LOL |
it should work but just in case, i would write or call primaluna and ask to be sure - they are in california, are usually quite responsive that way if something goes wrong when u use the tube they will more likely honor a warranty repair unsolicited rectifier tube advice -- for PL the buck stops at the Mullard or Amperex old stock 5AR4 GZ34 -- it is the best, period |
