Re: mic preamp modification

Hello John,

Dimmers for household applications still use 'phase-control turn-on', because the other techniques cost more.

Leviton and others also make special ones for ceiling fans because that noise can be really nasty. These often cost >$20 versus the usual $10 or so but I don't know if they just post-filter or whether they are really different architectures.

Regards, Joerg
