Eric, You can download the HP 521a frequency counter manual here: http://bama.edebris.com/manuals/hp/521a/ which has a description of the Phantastron circuit. You can also download the Tektronix 180a manual here: http://bama.edebris.com/manuals/tek/180a/ and have a look at the circuit diagram and also the description in the beginning about the frequency division.
