TUBE HELP with 5AR4 Rectifier

I just picked up a Tube Phono Preamp which uses a 5ar4 Rectifier tube...
I have (3) to choose from and would like to know which would work the best in the unit..

I know there are some really nice rectifier tubes out there but these are what I have to work with now...and I do wish I had some Phillips Miniwatts to try.

-10v 5Y3
0 5R4, 5R4-G
+15v 5U4-G
+15v 5U4-G, -GA, -GB [G=800ma-max, GA=900ma-max, GB=1000ma-max]
+20v GZ32 (Mullards own, 5V4 substitute)
+25v 5V4
+25v 5V4-G
+25v 5V4-GA
+45v 5AR4 / (GZ34)
