Yes. You can use both of them to get 26-0-26, I guess that would make it about 35V rectified, with 8ohm speakers and proper heatsink it should be fine. One of my chipamps is running on +/-36V after active filtering and 6ohm speakers, but I do not recommend that.

I will be pushing 150watt/8ohm speakers. I will have to use them together to get the power I want.

I guess i will be regulating the supply since i will have the needed overhead with 27v secondaries.

Connect the secondaries in series.
Leave the centre taps unconnected, but insulated.
You now have 26.5-0-26.5Vac at the mains voltage when you took your measurements.

If you do need an LV supply use one 13Vac and the series connection. That series connection is @ PSU Zero Volts.

On the other hand, would running 1 trafo per chip at 13-0-13 be enough?

look up the datasheet for your speakers and your chipamp.
