The aforementioned have contributed financially to the continuing triumph of 4hv.org. They are deserving of my most heartfelt thanks.
I ended up ordering the items shown in the photo. I wasn't looking very closely, because I didn't notice that the transformers were wired together!?!.
Can anyone explain why the transformers are wired together? It also looks like there is only one primary winding on what I presume is the "first" transformer. I'm pretty sure, but not certain, the nuts and bolts on each transformer are for mounting purposes and not primary connections.
Does anyone here have any experience with flybacks configured this way, and can shed some light on what is going on? The power supply the transformers are supposed to go into is rated at 35kV.
Some of the transformers in other, similar, listings are single units. In any event, they look like they might be good substitutes for some older flybacks that are meant for older CRT TVs.
Any information from someone who has used these transformers would be very welcome.

more voltage/power. I have a feeling that the mounting studs are connected internally to the primaries, as the other little wire pair seems way too small for >300 W of power (60 W refers to the laser output power), also 300 W would be pushing a single flyback to the limit. Or possibly the other core is being used as a current limiting ballast.

I'll test the flybacks when they arrive. Hopefully the nuts/bolts are primary connections. If they're really primaries, I'm guessing they are connected in parallel to boost the output voltage (like the stacked, diode coupled secondaries in later TV flybacks). It'll be an interesting experiment.
