RCA, RAYTHEON, GE, SYLVANIA, and other USA made NOS: This group is very diverse. The RCA, Raytheon, and Sylvania blackplates are among the best here. These are very musical tubes with air and sparkle at the top end, warmth in the mids, and great bass. The RCA are drop dead beautiful in guitar amps, even the lower priced greyplate and longplate versions. They also have a wonderful "phat" gritty sound when overdriven in these amps. The blackplates and most tubes made for organs are very quiet. The greyplate GE is an all-around nice-guy tube to listen to, the blackplate here possibly getting the nod for hi-fi use. The Sylvania greyplate and military versions are clean and a bit bright, but the Sylvania 6201 variants are very balanced and pleasant to listen to for hours. The RCA 6201 and 5965 is more like the Mullard, with a rich warmth and wide bandwidth. The computer type 6414 by Raytheon is a bargain since it is a 10,000 hour lifespan tube and has a great detailed top with some warmth in the lows. Currently, the USA made tubes are a nice surprise with their low prices as compared to the European types.
