I just got the latest Signal catalog. They list a part no. 36-20 which
with secondaries in parallel will produce 18.0 VAC @ 40 Amps.
I haven't worked out all the design equations given in the back of the
catalog but it looks like you might be able to use it for a 13.8 VDC supply
as long as the input voltage stays above about 100 VAC.

They list many other transformers.

I have no idea what these things cost new although I have bought several
Signal transformers from various Silicon Valley surplus stores.

Their address is:
