Good. That confirms what I thought then. I looked up my notes from
school (written with a quill on papyrus) and all I noted was that low
into high is fine but high into low isn't (with the standard garden hose
analogy). Nothing about what current issues might arise as a result of
putting a bigger impedance across a fixed voltage. Needless to say, the
little red schoolhouse I attended was focussed more on practical
applications than technical theory.

Right. I don't presently have any gear with a transformer output, but
if I did, I'd be looking at matching.

Thanks guys!
