    Hello Guys
    I am going to take a trip in the country
    tommorow to check out the above.
    The set has sound and the customer said the
    filaments are lit on the 3 tubes.
    Any ideas ....
    So I dont have to haul the thing back.

    Most common thing is bad flyback, HOT, and secondary rectifier (130v B+).
    Original flybacks are NLA, and the generic subs (Zenith uses these) are lasting
    about 1 year. About 20% of above failures are caused by bad HV
    splitter\bleeder assy.
