MONOBLOCK POWER AMPLIFIER

- JASON VICTOR SERINUS

It began with a bad outlet. Perhaps two weeks after my husband and visiting friend created several delightful holiday light displays in the living room, one of the living room outlets died. Every time I tried to plug in part of the light show, it, along with the living room sound system and reading lights, lost power. If the Grinch didn't exactly steal Christmas, he sure tried to guarantee it would arrive silently under the cover of darkness.

Evil Grinch proved no match for the visiting electrician. While our savior was here, I tapped his knowledge of the eccentricities of Port Townsend's electrical grid. When queried about the underground wiring to our house from the transformer across the street, he said, "Given the age of your house [1992], I am more than 99% certain that the wiring to the meter and your breaker panel is aluminum." After opening the panel, he shattered all illusions by declaring that the underground wiring from the main house to the second breaker panel in the detached music room was also aluminum.
