Will do next time it's not working. It decided to work again.

Oh really? That would be great...I have at least two with dead
flybacks.
*Heard of*. I have not ever fixed any myself. I'm running on VT525 nowadays.
Also have some VT420, VT510 and VT520...

What're the differences between the two again? I have a DEUNA for my
11/44 I still need to get rolling.
The DELUA is one board, while the DEUNA is two, I can tell you that much.
Right. In addition, the DEUNA have a PDP-11 at the heard, while the DELUA have
a 68K.
An -11 powering the NIC for a bigger -11. neat. ;)
So, at the microcode level, they are totally different.
The DELUA also have a better ethernet controller (a LANCE chip).
In short, the DELUA is improved in most ways. But it's fine details.

Hello!
The last time I had a monitor throw a spanner into its flyback, and
this was a long while ago, when I found out why they need them, it was
a problem to find a new one.
Then since the first repair firm fouled it up, the second stuffed a
generic inside and it continued to work for many more years.
(Actually they looked up what was the designated non manufacturer's
replacement number for it.)

Google. Worse thing that can happen is that the example will be
unknown to it.

My VT320 decided to fail last night.
It was running fine, I stepped away, returned to it off and repeatedly
clicking/ticking. It sounded like either a stuck relay or the flyback
arcing. The screen would occasionally flash and the current draw would
fluctuate between 2W and 17-25W until it eventually turned on and ran
fine.
Any theories? Should I distrust the VT320 or was it just something like a
stuck relay that's older than me? I grabbed pictures of the board but
they never seemed to actually get anywhere.

My God. Why do you run that garbage? Nobody with half a clue runs
that shit on purpose.
It was more reliable than my previous mailserver which is the absurdly sad
part.
I can set another mailserver up in a couple hours for $7/mo....I don't
know why I don't do that.

Electrolytic capacitors. Though that's a bit early for them to start
failing; VT320s aren't all that old, and I have yet to see a bad one.
That would explain the fluctuating voltage until everything settled.
