A 5-1/2 digit Fluke 8800A bench multimeter from around 1980 that I bought
for $25 still matches a calibrated voltage standard to the last count.
Industry dumps equipment (and people) when age makes their reliability
questionable.

I picked up (Ebay) a Fluke 8010A and a 37 a few years ago. Was
hoping for the best but they both need work. Would really like to get
the 37 working. It's a lot like my 87 but not quite the same spec. Has
a bargraph display which can be handy when tuning circuits. Made to
sit on a bench or portable. Uses a 9v battery, same as 87 series.
Suspect the input protection, "Varistors" maybe flakey. I ordered some
in but have been too lazy to seriously dig into it🤷 The 8010A may need
some serious switch work/cleaning. Used to see those switches in radio
equipment and they were prone for dirt/noise. Royal pain to desolder
and probably unobtanium to replace nowadays. So need to be carefully
disassembled and cleaned...

I don't lack for projects just the drive to do it😑
