I refreshed a 625 and it wasn’t that tricky. If you have a lamp limiter it might be an idea to see if it’s working.....definitely worth making one if not to avoid very frustrating mishaps. My 625 had a lot of bulbs out which I replaced with led’s, the main smoothing cans were bulged and leaking (common on these) and needed replacing. Cleaning the switches with servisol (carefully) is always one of the first things to do. Again from memory there weren’t that many caps on the 625 so you could just do the lot if planning to keep it. I think the resistors are film so should be fine but measure with a dvm if unsure. The transistors on mike were all fine. One “feature” is the tuning scale only lights up when the tuner input is selected. These were never high end so I wouldn’t go bonkers on “audiophile” components...sound wise I preferred the earlier 500 series.....they do look nice though!
