Can this be fixed?

Looks like the adhesive just broke loose. Or the Xformer overheated, expanded and broke loose the adhesive from the mounting plate. I would take some ohm and voltage readings before attempting the repair. Also check the windings for shorts. She may be smoked open or shorted.
If all checks out ok, then maybe apply heat with heat gun or SMALL butane torch to heat the plate original glue and try to peel off. Then remove the old stuff and apply some 2 part clear epoxy that withstands high heat to hold her back down. Just my skinned knuckled mechanic 2 cents. YMMV. Good luck to ya!

Yes, definitely dropped, the flange that holds the "laminate" core for the wrap itself - shifted - there's a lot of weight bearing down on the mount and the "glue" is simple adhesive - like high voltage stuff - rubber cement - so to see the shift like that - looks like at LEAST a 3 foot drop. The "glue" can also be the paper and lacquer applied to "seal" the winds - and you see the lacquer and paper peel...
IT ain't light either - F= M x A - someone looked like they got pissed or shipped you stuff they got from someone else. Those pics show a rebuild in progress - so some arrived in good shape - not sure if this drop was a recent one or someones' trying to whitewash an "error"
There is overspray present on the anodized/zinc'd winding cover - not sure if someone was trying to hide overheating toast damage with fresh enamel or just dressing this up - but the "Core" seems clean - just now a bent wreck.

The results you got are exactly the reason I always recommend using PayPal. I have not lost any money to bad vendors on eBay. Does it work at all?
If not check all of the tubes and be sure they are seated fully.

Oddly enough, this is why the manufacturer (or dealer) insists on removing the power transformer before you ship one of these. They make it easy, providing connectors on all the transformer wires, and a rope handle through the core.
A new one arrives with the transformer in a separate carton. Installing it is not a big deal.
But shipping it with the transformer in place is risky.
As you discovered.

Well I managed to bend the transformer back to center and then stood on it a few times with a towel on it and squished it to 95% of original.
Seems to be like brand new. Not bad for free.

A single Gu74b? I'd stock up on some spare tubes. A few more if you're going to run it that hard. Russian tubes used to be dirt cheap but as the supply is getting smaller the price keeps going up. The part about squishing the transformer is kind of scary. Be sure the proper size fuses are installed and that it is grounded.
