I purchased all of my tubes from TheTubeStore.com. They have an outstanding website and excellent service. For the driver tubes I decided to use JAN-Philips 7308 Low Noise tubes in place of the stock Russian Sovtek 6922's. The 7308's are a rugged military replacement for the 6922 tubes. JAN means "Joint Army Navy" and the tubes were made by Philips. I used Russian made Svetlana 6550C power tubes which is what the Audio Research factory uses.
