Phil,
Just the opposite, the 5AR4 is the magical rectifier that makes a golden ear amplifier come alive. The 5V4 is the TV damper tube that is only of interest to antique TV collectors. I've used it in 502 scopes and seems to work reliably.

Hi Chuck,
While I was reading your comment to Jamie, I note with interest your suggestion that a 5AR4 is of little demand.? This tube number jogged my memory, and I found it easily in the Service Manual for my HP 200CD Signal Generator, where it is employed as a rectifier tube... I'm hoping that you're right about that, because I could use one for a spare. ;)

BTW a workable replacement for the 5AR4 is a 5V4 again a TV damper tube and very little demand outside of the TV collector community.
