[Avodah] microphones on shabbat

[Eli Turkel]

In his most recent weekly shiur, Rav Asher Zelig Weiss expressed
himself about electricity in almost exactly the same terms as RMB does
here: the prohibition was determined first, and then the poskim looked
around for a category to fit it into.>>

It is clear that this is the opinion of RSZA about electricity. He
disagrees with CI
about boneh and with others about nolad. He doesn't seem to have any real
reason to prohibit electricity (without light/heat) on shabbat nevertheless he
certainly never allowed one to turn on electricity on shabbat.
