Re: Big Capacitor?
A bit off topic, but hopefully within reason.
These are DC caps used to stiffen the supply of power to the
big-wattage amps. It takes the "sudden load" off of the alternator
when the big-bass hits happen. Keeps the headlights from dimming
(as much) when the bass really sucks all the power up from the amp.
A few farads at 16v is a very common number. I have 3 16v 64000mfd
caps here next to me. They are useless for TC work, but do a great
job at blowing up small pieces of wire, of delivering a super-nasty
flash/bang if shorted. I run them in parallel and have fun
watching the wires (2 helical coils, placed next to each other)
jump an inch or so when I short the caps. They heat up fast in
that useage. But for stiffening the supply for my surround-sound
sub's amp, they work wonders!!! Think of it as PFC for the amp ;)
You'd really be amazed what a mofset-based amp can draw. But as
with solid-state vs toobs...a nice warm 833a would push the sub
just as hard (if not better!), and provide a nice comforting light
to read by ;)
