Most of the 76 sound similar. I like the Visseaux 76, World War II era RCA CRC 76, National Union, Tung-Sol, Raytheon, Philco and Sylvania. Not necessarily in that order, but the Visseaux is the best of the 76 and the rarest.
The 37 are all the same sound as the 76 just a bit less gain so I quit collecting them unless they are meshplate. My favorites here are Sylvania and Philco meshplate globes. Equally as good are the Silvertone meshplate in the ST envelope. Silvertone is the Sears Roebuck house brand and they used many different manufacturers over the years so I don't know who supplied Sears with this tube. I haven't been able to match up the meshplate with other known types so it remains a bit of a mystery. This tube is top supported and not free floating like the globes so has a slightly different sound than the globes. Maybe tighter and less ethereal than the globes because the structure is a little more damped and less microphonic. A real winner and cheaper than the globes.
I use these tubes in a DIY Bruce Berman preamp that has a separate power supply chassis so I haven't had any trouble with these tubes being noisy or overly microphonic. All these round plate tubes are really wonderful.
