Thanks "Newbee" and " Chams uk". I too bought some 5751 lately (Sylvania Gold brand 3 Mica Black Plate Goldpins, RCA Black Plate 3 Mica, GE Black Plate 3 mica, Raytheon, Tungsol etc.)and prefer to use it , than the 12AX7's, in my application.
Life Expectancy of a NOS 5751 Vacuum Tube
Hello,
Just curious, can anybody shed a light on how long a typical NOS 5751 vacuum tube last assuming normal use (2-4 hours a day)? I found the same info for the 12AX7 (same family or comparable to a 5751 but with higher gain)but not for the 5751. Your input is greatly appreciated.
regards
