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..

SOVTEK
RUBY
JJ

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.

Thanx for some of your suggestions....Right now I am using the RUBY(chinese) which sounds really nice..
I contacted Kevin at Upscale and ordered up a Japanese 5ar4/gz34 which is a copy of the Mullard.... Should be here on Thursday and will give it a try..Seems to be a likeable tube to some tastes according to user chats...
