Large heavy duty toroidal transformer. Antrim 3671G. 2 x 120v input. 24-19-0-19-24v output. 19v @ 4A. 24v @ 1.5A. These have been in storage for 20 years and unused.

Not too sure on the wiring of these other than the two brown and pink pairs are the primaries and the other two groups of wires will be two secondaries. I assume these are 2 pairs of 0-19-24v outputs.

These are fairly big. 110mm diameter. 50mm thick. Weight is just over 2kg.

Some of these don't have the voltage and current ratings shown as in the picture and just have the part number marked on them but they are all the same other than that.
