    Suffix Z indicates an undefined number of chassis variations, where one ore more tubes of the basic complement were replaced.

    Just after WW2 there was some material shortage. Zenith had to modify the basic model to accept available alternative tube types. Hence Octal, Lock-in and 7pin miniature types had to be mutually adapted by changing the sockets. Such factory modified chassis and radio models got the suffix Z. Zenith also recommended these alterations for service. Such models maintained of course the initial name without Z. All such numerous variant combinations can only be distinguished by close examination, but not by just a view.

    A single chassis may contain octal, lock-in, and miniature buttom tubes. If an original tube is replaced with an alternate, the socket must also be replaced.

    Listed above is the basic tube complement.
    Alternatives that may be found are as follows:
    Original: Alternate:
    12SA7GT.. 12BE6 or 14Q7
    12SQ7GT.. 12AT6
    35Z5GT...... 35W4
