Aric Audio Systems Unlimited Preamp

@kalali I would not recommend a pair of OC3s as the regulators as they'll drop too much voltage which will cause the dropper resistor to absorb too much current and run very hot (hotter than it's rated). Using the 5U4GB I would recommend the OC3 and OD3 which will provide a much more ideal voltage to other components in the preamp. It will drop very little voltage, and provides a slightly more laid back presentation :-) Aric

I misspoke about delivery of the tubes. I should have them by 12/10.  I'm really looking forward to this experiment. 

Thanks Aric. Let's see how this works out in rocray's system, depending on his upstream/downstream components but in my current system which includes mostly tube electronics both upstream and downstream of the preamp, a more "laid back" presentation may not be as desirable. An all solid state system may benefit more from this change, albeit it'll probably be a very subtle change.

Well my Sylvania 5U4GB and GE OC3 showed up and are installed and running. The first thing I noticed was I had to turn the gain down. I'm letting things settle in a  bit. There seems to be a little more holography happening. I really didn't think that was possible. 
  
   tubepower,thanks for the recommendation,and Aric,thanks for the guidance in making this happen!  I'll post some more impressions as I get more time with this combination.
