It gets here and two of the transformers aren’t even screwed in, and the tiny nuts are bouncing around in the box.
I got them about as secured as they’re going to get with one nut each without taking the whole thing apart… probably not a big risk to power this thing on? Or should I just ship them off?

Edit:
still basically came out ahead but not so lucky
I have a known good VC528 to compare both to.
The one with all the appropriate transformer screws matched almost perfectly with my good one, except it cuts out if you jiggle the 6/-12 HPF switch.
The one missing the screws (but is held in with one screw) is 1.5 db too hot, but you can adjust it down a click or two at the fader or trim.
I haven’t listened to them yer but tested them with test tones. Will just use them and deal until I find a tech in Houston I can drop them off to.
