Is this the particular tube type# specified for your Mapletree Audio Ultra 4A? Because it is a metal tube intended for ac/dc radios & has a single cathode common to a shared grid for both anodes = not easily implemented in typical 2-stage phono circuts & certrainly not swappable into existing circuts that were not designed for this specific tube type.
