I can"t really tell from the Picture but those Transformers look a bit too small to Power a Chip amp...There is nothing in the Pic to really tell the size of it but from first impressions it doesn"t look very big....

do you know the power rateings of these transformers??

You connect them in parallel, but make sure you get the phasing correct or you won't get anything out except heat. The correct phasing can usually be identified by the colors of the lead wires or dots marked on the terminals if there are no lead wires.

Dual 115V primaries allow the transformer to be used for 230V input by connecting the windings in series (again, be careful of phasing).

If you have a transformer that has dual 115V primaries and 50V secondary but you need a transformer with a 25V secondary, you can just wire the primaries in series, plug into 115V and you'll get 25V out.

No, I'm afraid I don't. There were no P/N markings on the xfmr, so I don't really know. I'm planning on using it for a small guitar amp, so I don't need anything huge.
