I have 2 of them & on one it appears that the input jack has been pushed in. Is this a tricky repair or is it fairly accessible so I can re-mount or replace the jack? It's useless without it, so I should probably try, but figured I'd go in search or others more knowledgeable first.

That amp has a fully enclosed type plastic Jack soldered to the amps circuit board.
Replacements jacks can be had and just soldered in once you cut and break apart the old Jack so you can pull out each soldered point of the Jack one at a time, that is if the Jack is badly busted, if your good at unsoldering and prying things out, or have a manual solder sucker then may get the Jack out without having to bust it up first
Sometimes one or more of there soldered points to the board is just fractured as seen by the ring around it and needs to be resoldered, and in that case concider yourself lucky .
Now the hard part, getting the F Ing amp out of its cabinet is a Bear!
Once you remove the screws that hold the chassis in the tuck & roll covering makes for no clearance to just simply slid the amp out.
I could work out no other way on the one that I worked on but to pry it out with a wide flat blade screw driver until I got it out of the cabinet far enough to just hold the chassis well, and yes I did do some damage to the T&C covering on the back side.
Just note that if the Jack still looks good but just has a busted solder joint or two that many times its bent up on the inside and will not make a good solid connection with your cable end even once the busted Jack to board points are resoldered, so check first that the cabke end does not rock around in the Jack more than say it rocks around in the amps Headphone jack because if it does , then like I said its shot internally !
To stop from breaking these crappy plastic input jacks in the first place when you play the amp just rap your cord around the amps handle once or twice , that way when you by mistake trip on the cord again you just knock the amp over without damage to the Jack again!

Thanks! Of course, I'm hoping it just lost the lock nut & got pushed back A LITTLE, & just needs to have a new lock nut on & will be OK. I also know that the chance of that being the case is slim & none! Thanks for the tips & I'll keep you posted on my success or lack thereof.
Thanks Again,
Tony
