Additionally:
Expect to replace electrolytic caps in the power supply and audio amplifier sections. Not a big deal, no different than recapping a vintage radio, really.
If you are going to work on several receivers, a transistor tester would be a good thing to have. But if this will be your only receiver, than you can get by with the diode checker function of your DMM - or even the ohmmeter function in a pinch. I bought a Heathkit transistor tester that found bad transistors in my Fisher 4400 that were only showing as questionable on my DMM. That 4400 is now on the desk of my home office and is my "daily driver." It uses germanium outputs. But since I replaced all of the electrolytics in the power supply and audio amplifier sections, it should be good to go for several years.
I started working on a Fisher 170 but had to quit when other things came up. I also have a mostly finished 700-T and a partially finished 440-T waiting for me to get back to them. Not to mention the 220-T...
