Excellent recommendation to read Joe's Tube Lore. Here is the "punch line" --

Like your friend, Joe's Tube Lore recommends using 5751s in place of 12ax7s. You have to check and be sure your amp can deal with 5751s though. I checked for my Art Audio Vinyl One phono preamp, and I was not allowed to substitute 5751s. Bummer. Here's the punch line from the very long tube lore:

"....lets have a look at the cream of the 5751 crop....

... my best of the best short list include the following:

GE black plate (definitely not to be confused with the grey plate version)
Tung Sol
Raytheon
Sylvania black plate government contract gold labels (JHS, CAA, etc..)
Sylvania Gold Brand black plate
Sylvania Gold Brand grey plate - gold pin"
