How much do voltage regulator tubes affect performance?

I have an Aric Audio Unlimited all tube preamp that runs a pair of OD3 or OD3a voltage regulator tubes. I'm going vintage Telefunken for the rectifier and output tubes. I can't find if Telefunken even made any voltage regulators. I'm using General Electric vintage ones right now and it sounds good to me. Just wondering if their are "premium" voltage regulator OD3 or Od3a tubes available.  Or if it even matters that much. 

Thanks guys!

Amperex does make one I see now. Hmm swear it didn’t show up on my last ebay or Google search. Weird. Time to see what happens lol.

Thanks holmz. Appreciate it.

  1. I wouldn’t get it for sonics
  2. But it is always good to have a spare ready
    1. Retire the current one as a spare if the new one sounds better.

You pick, there’s no wrong answer 😎

It shouldn't make any difference at all unless the tube fires at a different voltage.
