You must have got lucky & got a Tek 2465 without RIFAs
in the PSU or a Schaffner line filter, I think one of mine didn't have them.
Also the Sprague electrolytics (alu can with red seals) in the PSU like to leak corrosive electrolyte, maybe yours has a different brand fitted.
Anyone that does re-cap the PSU of a 2445/2465 series scope should note one of the manuals has an error, two capacitors are swapped on the diagram, if followed you end up with a low voltage capacitor fitted to a high voltage rail, with resulting smoke, this was covered in an eevblog video a few years ago where this happened.
