Re: OT: feedback resistors in PAs

The half gauss of the earth's magnetic field is small taters.
Yes, but appreciable anyway: Lorentz induction through an area of several cm2 varying about one thousandth by mechanical vibration at 1,000Hz in a field of 0.5gauss would give something in the tens of microvolts, so less than -100dB.
OK, just appreciable ;-)
