The 80-series Hypermetrons used a new chassis similar to the 70 series but with three RF amps in place of the 70's two.  The 89 (60 cycle) and 892 (25 cycle) used the same cabinet as the previous season's 79.  The 82 (60 cycle) and 822 (25 cycle) used a unique cabinet.

The tube complement is: 3 x 24 R.F., 24 detector, 27 1st audio, 2 x 27 push-pull driver, 2 x 45 push-pull output, 80 rectifier.  This set is currently in the shop for chassis restoration and minor cabinet work.  The illustration is actually a 79.  When I finish the 89 I'll need help placing it in position for a photograph - it is the heaviest set in my collection.  The cabinet is solid wood, has six legs and needs them all.

The 1942 Zenith Radios sales brochure had this description:

The "automatic tuning" is a set of six presets with trimmer caps for the R.F. stage and slug-tuned coils for the oscillator.  Frequency coverage in three bands is 540-1600 kc., 1500-5200 kc. and 5700-18,300 kc.  The tube complement is: 7G7-1232 R.F., 6J5GT oscillator, 6AG8 mixer, 6K7G I.F., 6J5GT detector, 6F5G 1st A.F., 6J5G inverter, 2 x 6V6G push-pull output, 5Y4G rectifier.  This set is currently under restoration - the illustration is from the 1942 sales brochure.
