In my own case the older transformer is going to be the protected load
and one of the newer transformers is likely going to be in the buck
position. Insulation breakdown could be a problem but I think that's not
very likely (in my applications) even with an older transformer. In any
event - that's what fuses are for. You DO use those don't you? I'm
pretty sure they have saved my hardware, my home, and possibly my life
several times.

John Forster made a usable diagram and it is exactly the picture I got
from the description by John  WA4WDL. Somebody else referred to the two
windings (bucking transformer) being in series aiding but my
understanding is that it's series opposing. The distinction, at least in
my easily confused mind, is not trivial. I often struggle to keep terms
and what they describe straight so I may have it wrong. There is also a
link to a PDF file and I am going to grab a copy of that. When I go on a
trip I have paper maps, a printout from google maps, and a GPS device
telling me when to turn left. It never hurts to compare what you see on
the road (chassis) in front of you with the "maps" no matter you have
been down the road before. I've used a bucking transformer a couple of
times before. Not recently.
