● “RCA VT-231 grey-bottles are much warmer and have a grand presentation with accentuated reverb. [compared to Ken-Rad and Sylvania VT-231 combo]” –Glod
● "As far as lushness goes the 1940's RCA grey glass is the one to go for." -RobN [in personal correspondence with author]
● “The warmest, best tonally is the early grey glass RCA VT-231. This one has very strong bass, a bit less defined, but an incredible rich midrange.” –Robert H
● “Yes, the RCA VT-231 is a bit syrupy. It certainly doesn't have the openess and detail of, say, the Sylvania VT-231. But it's TONALITY is just, well...right. The sound of musical instruments - their tonality - is simply the correct one. I just love this tube. So musical. It's sorta like a real babe, with killer knockers, but she's got a little too much around the middle. You know there's something not perfect, BUT - it just feels so damn good you can't keep yourself from going back.” –Robert H
● “Here we get into murky territory. RCA produced a grey glass 6SN7GT with side micas straight through from 1942 until at least 1956, and there is a great deal of sonic variation among tubes within that period. None are bad. But the early one sound far better. This is one of my favorite 6SN7's, but let's face it - it is very warm and lush, has a huge soundstage and huge bloom - not for Cary owners (for example) whose amps are already tubby sounding. In a good, neutral tube amp - which is what a good tube amp is, actually - this tube is a king. But be VERY careful about the vintage. Early ones have the magic. Later ones are good but no moondust.” –Robert H. (in personal correspondence)
