I have two VT220s. One of them has a PCB mounted flyback transformer, the other
one has it on the chassis connected via wires.  Mine have these part numbers:

16-26299-01 (probably the PCB mounting one)

Apart from the mounting, they look very similar.  I examined the two PCBs and
I couldn't find any component differences but I could have missed something.

One of mine has failed, most likely the transformer is the problem.  I think it
is the PCB mounted one but it was a while ago and I forget the details now. I
went looking for a replacement but I didn't manage to find one at the time.
