The ARC Ref 2 uses (1) 5AR4, (1) 6L6GC, and (1) 6922 tubes in the power supply section. Rectifier might be the wrong word.

It turned out 1/2 of the 6L6GC I had purchased were bad. The 5AR4 tubes were "unstable" during the warm up stage, but then they are fine after the initial warm up. Nick suspect that there might be mini arcing when they were warming up. Well, I guess I won't be plugging them into the preamp anymore.
