All American canner vs autoclave

I thought I might buy one of their autoclaves, but looking at their site I notice it has a 60 minute bell timer. I think this means no programmable cook time/auto shutoff. It also has a temp knob, so no pre set temp/pressure.
So other than not needing a stove, is there any reason to buy their autoclave over a PC?
Also, I think I read here that the large sterilizer holds 14 quart jars. Can anyone confirm this? I currently use a 930, thinking about upgrading. I might end up buying a 941.
Are there other autoclave brands that allow programming time and temp? That's really what I want, something I can set and forget.

The 75x is great but has less internal volume than a 941 due to the element. I've never used the bell timer thing, just ignore it if you get one.
The thermostat on the 75x is pretty sweet, just plug it into a timer that will handle it, which will make it as close to set and forget as you can get.
I've owned both the 941 and the 75x. I like them both, but you can fit more bags into the 941. The 75x is a bit more convenient.
The advantage of the autoclave is that the stop cock prevents water loss during the cycle. I run my bags for 4 hours, I'd be cautious about that length of cycle using just a weight.
The 75x takes about an hour to get hot enough to steam, then about another 30 to 40 mins to hit temps. I vent for 20 mins so you're looking at nearly 2 hours to even start the cycle. The 941 can get up to temps a bit quicker because of the external heat source.

p9hu7 beat me to a few of these while I was typing, but I'll post it anyway.
The PC versions are slightly larger internally than the sterilizers and are lighter.
The sterilizer version's bell timer is only a notification and does not control the power to the unit. You can use it to notify you to check for steam/close the valve after venting though.
The temp is controlled by the rotary knob on the front. You'll calibrate it on the first run by heating it on full power then as soon as it hits the desired pressure start turning down the power until it turn off the heater. It will turn off until the pressure drops a couple psi then kick back on until it reaches the previous pressure.
You can get inline digital timers at home improvement stores/amazon/ebay for $20-$30. Just make sure they are rated for 1600w.

Your 8" stove element is 2600 watts. The 75X is only 1650 watts. Fucking anaemic!
Using a 1941X or 941 modified, on a real stove or commercial 240v burner is VASTLY superior if your time is worth anything.
I supposed the 75x has a less need for babysitting, but you could do more in less time on a 941 were you so inclined.

Thanks for the input guys. I'm leaning toward the 941. 19 jars at a time is pretty nice though it does seem with an inline timer the 75x can maintain temp and switch off on time.

Trust me, running that amount of jars definitely sucks. You'll want to use bags, its far more efficient and honestly just a whole lot easier and less tedious.
If you can afford it get the 1941x, instead of the 941 pressure canner. If you're spending that much money already you'll kick yourself for getting the pc over the autoclave.

It's a lot of jars.
I do monotubs, 5 jars of spawn, comes out to 10-12 cups of hydrated grain. Can anyone suggest a bag size/brand? And how do they seal? I have an impulse sealer. And they are kneaded instead of a jar shake?
And how many bags will fit in a 75X autoclave? How many in the 941?
Is the cook time different with the bags holding more spawn?
Sorry for all the questions. I've been doing this for years so this would be a major change for me.

Well I put 9x 3 full quart (4 myco quart) bags into my 75x. Filthy does 11, I believe TedsDead crams 13.
You can get a few more into a 941.
Get the 3t Unicorn bags with .2 micron filter.
You will need to sterilize them for 3.5 to 4 hours for that much grain.
You can either wrap or accordion fold your bags and they seal in the pc, use a good AIE brand 5 mm impulse sealer post inoculation to seal bags.

Don't mean to butt in but I'm planning to start bags pretty soon and was gonna get a cheap $50 sealer, is there a big difference between those and the more expensive AIE if I'm not gonna be running more than 10 bags a week? Also a 12 inch sealer is more than sufficient for the 3T bags right?

12 inch is fine, but you will likely be extremely disappointed with a cheap sealer. Theres tons of threads saying as much, people almost always regret it. The issue is that the sealer needs to be able to seal without melting holes or missing spots along the seam.

My 3 favorite pieces of equipment are my hood, 75x, and my 16" AIE sealer. Its a beast of a machine.

Nice. you can seal the large bags with the gussets folded out the long way with a 16" sealer. Always kicked myself for getting the 12". Do you do yours that way or just regular tucked gussets?
2 layers would give an obviously superior seal to the tucked gussets 2 layerss in the middle and 4 layers on the gussets. So that's 4.4 mil in the middle and 8.8 mil on the edges. I have found a lot of seal failures on this area when not using full power and with weaker sealers.

I got the large one with that in mind. I want to straight seal large XLS bags when doing gourmet blocks. I straight seal regular 3t bags as well.

You can always get an outlet timer for the 75x. I've always felt more comfortable setting and forgetting the electric model than the regular ones. The latter requires some tinkering with heat management plus you have to worry about fuel running out (I use a gas canister stove). When I used the non electric AA's I never felt comfortable leaving the room.
The timer on the 75x is manual which is pretty useless—but these models were made decades ago. I heard that AA is in the works of a new computerized model which updates some of the problems you pointed out.
