I originally used a 184 Time Mark Generator for some of my broadcast 
measurements where I needed 10 kHz markers throughout the AM 
broadcast band.  I don't recall it having drift anywhere near that 
amount.  I wonder if your oscillator tube is on the verge of croaking 
or if the stone has become feeble.  I don't think these devices 
needed a great deal of accuracy, certainly by "our" standards, just 
enough to set the time base adjustments in a scope.
