	Good for you! Warms the cockles of my EE heart, lemme tell ya ..:-)

	Even better than the coup I pulled off a few weeks ago with a
	replacement power antenna.  The old Bosch unit was slower than
	molasses, the timer relay was adjusted to match (luckily I knew
	enough German to realize what Zeit Relais meant!).  The new
	one was more than twice as fast and cost a third as much.

	Ten years of college (actually two years of hobbying in high-school)
	to the rescue! Yanked the relay open, located the biggest electrolytic
	cap. I could find (200 uF) and replaced it with a 100 uF component
	from my drawer-full of Radio Shack detritus.  Works like a charm,
	and wins the power-antenna drags hands-down :-)

	-Arun

	PS: The car will probably self-destruct in months, though : the
	new antenna is Japanese!
