Does anybody know what component that is between the collector of the transistor and the load? I have never seen anything like this and it is not in any of my reference books. Thanks.
We received this from a customer and it is designed for a burn-in test for multiple transformers with the secondary loaded. But I agree; this is not the way I would have done it!
If it is a switch or some sort of circuit protection, then it is definitely in the wrong spot. Perhaps it is meant to be a test point?
Fine,
You have shown us a schematic as you got it. why not take a real photo of the portion of circuit?
I presume it to be ferrite bead for RF Higher frequencies or Harmonics not to interfere with the working.
As rightly pointed by Nigel, the circuit appears weird. I imagine that the designer is extracting multiple outputs from one input and at different impedances, as already indicated by you.

We do not have the circuit; the customer send us this schematic as part of their spec sheet. What the customer wants us to do is load the secondaries and excite the primaries with this circuit.
