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=F0=9F=A4=B7 The 8010A ma= y 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=F0=9F=98=91 --=20 Leon Fisk Grand Rapids MI
