While you probably like your 7272, units such as those and other cassette decks usually aren't recapped, due to the large amount of small caps, labor involved, and lower value of these units. I typically haven't recapped cassette decks, primarily because the caps in them are usually reading fine, not being real high, real low, or high ESR, and many times you need to totally dismantle the unit to get to the caps. I have recapped a few Reel to Reels, but that is usually as a result of other repairs and "why not replace the caps while I am here" and being easier to rwplace than on most cassette decks.
I have calibrated test tapes for reel to reel, and a few for cassette, which is why I can replace caps on these units. If you do decide to replace the caps, remember that alignment may be necessary (Record levels, play levels, equalization, bias etc)
