Tubes Asylum Questions about tubes and gear that glows. FAQ |

I was researching vintage 12AX7 tubes, and a pattern emerged - over a variety of brands and countries of origin, "long plates" are more highly sought after and command a higher price. (Probably old news to tube fans.)
My question - is there actually a physical characteristic of a longer plate that is beneficial for audio sound quality ? OR is it simply a matter of the longer plates being used during a particular time period in the 1950s when the 12AX7 tubes were better quality ?
(If it really is the length of the plates, then it should also correlate with current production tubes as well, in theory.)

- The point is that you can't tell how a tube sounds by looking at it. - Chris O 12:14:44 07/19/12 (1)
