I have Service Manuals for 465, 465B and 466 scopes. The 465 and 466 would
appear to have pretty much the same fan motor and circuit. The circuit
number for the fan motor is B1690 in both cases, with Tek part number

might know more certain from experience. However, the 465B is a rather
different thing; the fan motor isn't the same as the 465 and 466. I hope
this helps.
