Winter has returned to Cherry Valley, New York, and I'm reminded of a bad habit that I used to conceal: On cold mornings I started my car <I>well</I> before driving off, then actually weighted down the accelerator pedal&#151;with the heavy socket tray from my toolbox&#151;in an effort to keep the idle high, and thus more quickly warm the windshield and the interior. Whether my lazy trick had the desired effect is a matter of some debate, but I wish now that I hadn't been so wasteful and so casually fouled the air.

The 78rpm train has been derailed for the time being. The KAB Souvenir VSP Mk.II phono preamplifier, which I intended to review in this space, has yet to arrive from its manufacturer, owing to a delay in the availability of certain parts. The Elberg MD12 Mk.III preamp has yet to arrive from <I>its</I> manufacturer, owing to a recent redesign. The Sentec EQ-10 preamp is here but has a broken switch I haven't got around to fixing. The McIntosh C-8 preamp, a lovely vintage piece that's available for peanuts on the used market, is still undergoing renovation by someone who isn't me.

Determining whether an idea is brilliant or off the wall is often a matter of perspective&#151;and of looking at the results that follow from the idea. Take the notion of AC regeneration. AC is what comes from the wall socket, courtesy a network of power-generation plants, and it's specified as having a certain voltage and frequency, with the amount of current limited by fuses or circuit breakers in the electrical panel of the house or apartment. Audio components&#151;other than those powered by batteries&#151;are designed to convert this alternating current (AC) to direct current (DC), then produce variable AC that drives the speakers to produce a facsimile of that signal. In short, AC provides the raw material used by audio components to do their job.
