I have a 6B4G SET and I now have 4 sets of NOS tubes: Sylvania, Tung-Sol and Raytheon (which are probably Sylvania-made though) 6B4G, along with unbranded 6C4C.
They're all better than the unbranded 6C4C. In my amp they all sound virtually indistinguishable but my amp is fairly inexpensive (e.g., Edcor OPT).
The advantage of 6B4G is cheaper NOS, which are still plentiful. The disadvantage is the difficuly in keeping the noise level down. Swings and roundabouts.
Heck, if you're interested, I'd consider selling you one of my NOS sets. Let me know.
