What type of tubes are you asking about; small signal tubes, octals, power tubes?
My favorite tubes for sonics are 6SN7GT... 1940s Tung Sol oval plates, RCA Greyglass, short bottle.
12AU7.. Brimar CV4003 boxplate, RCA blackplates, 1950s Mullard long plate square getter, Tung Sol 1940s blackglass, RCA 5814A Command Series.
12AX7... Brimar CV 4004, early Amperex/Philips Holland.
Also depends on the tube position such as gain, driver, phase inverter, cathode follower.
