not a power supply decoupling resistor. I would recommend going to the Jensen TransformerWebsite.

Look in SCHEMATICS
APP AS016 and a bunch of other schematics have directions on how to implement it. You need to match the 6.8k resistors to better than .01 % with a digital VOM so buy more than two. Buy like a 100 and go through them. You can also buy a Power One or Condor 48 volt power supply that has an adjustment pot on it. Yes, you need a voltage regulator as a ripple filter. Some other schematics have LEDs and a charging cap and a switch. You just have to search and look around. Good luck! Ray

Follow Ups:
FYI - I have a Power One power supply to power 4 mic pre cards, and it's been working like a champ for about 25 years. (Although I'm using outboard Studer 48v for phantom.)
