Been wanting an All American for ages, and keeping an eye on local ads finally paid off! Thinking of getting back some precious freezer space and starting off by canning some stock.

Nice! Basically impossible to find here in Japan. Lehmen’s out of Ohio used to ship internationally, but quit by the time I was ready to buy one and did not respond to my email to try to work anything out (it was a multi-thousand dollar order of a bunch of stuff and I live near a port).
I know absolutely nothing about canning. Why does it require a pressure vessel?
Spores of Clostridium botulinum can survive boiling temperatures and can thus start to multiply if the food in question if the pH is above 4.8 and has non-lactose carbohydrates and is in oxygen free envioriment.
In practice this means that low acid foods such as beans or meats could get infected and thus be contaminated with a deadly neurotoxin producing bacteria. It is the same bacteria why infants shouldn’t eat honey.
Pressure vessel allows you to increase the temperature to above 100°C thus killing the spores and allowing you to can those low acid foods safely
Nice find! Always wanted one but its a no go with a glasstop stove so Im out of luck.
Sorry to post on a very old thread, but it depends on your stove, my old glass top stove handled my All American model 921 with 18 jars in it, I was very very careful, but the manual said the glass could handle the weight (just).
I actually got a coil top since this comment! Old stove kicked the bucket so I decided to go for coils. Havent gotten a pressure cooker yet though.
Glad its an option for those with glasstop though.
