I do not know the answer to that question. Chuck indicates that it to prevent being killed by a high current- high voltage from an accidental shock. What I do know is that the Tektronix specifications for the 152-0552-00 call for a series resistance of 510k ohms. This is found in the TEKTRONIX Cross Reference manual. The pictures of a DIY multiplier by member Marcus PP5MS can be seen in a series of pictures at this link:
Marcus - PP5MS 465-475 HV multiplier
His version clearly shows a resistor in series. His looks like 47K Ohm to me. His x ray also shows something in the Anode wire that could be a resistor.
I do not know all the technical reasons for this. But the specification is there, so there must be a good reason for this resistance.
I will defer to the sharper members to explain it to me.
If I build one of these, I want to match the original as closely as possible.
