Not only are they very nice instruments, they are (to me, anyway) enjoyable to work on - anything other than the thermocouple or meter movement can be repaired and it is easy to access the subsections.? I have several different iterations of DIY replacement boards for them and have one as a semi-permanent test bed on a bench shelf to try out different ideas.? And, of course, one is used frequently for measuring power supply noise? - my main use for it, actually.
I've never had to repair it, but I have a 3400A that I really like as well. A friend who died left me a second one; I've not checked it out yet.
