How is this possible?

When you unplug a box and remove all batteries, why does it still "spike" momentarily if you turn it on? How is it possible for a box to "store" a little bit of power? I don't see how a transformer could "store" any power.

Exactly, the transformer doesn't store power, the bulk capacitors do.

I Agree

i have noticed this too, especially on hitachis Nod Yes

So the capacitators are those things that look like silos or cylinders, right? What, are they filled with metallic chemicals that can store power? I don't really know how they work.

yes the capacitors hold the power, they are squished up discs of paper and honey wrapped in a layer of metal to avoid any interference. they provide capacitance

the resistors work in a similar fashion only use butter and oil condensed due to the resistant yet conductive properties. these, believe it or not, provide resistance!

yes i know more than well the after power of caps,especially when i used to think i was a tv repair man,i had loads of belts from 400v caps in the power supplies..i'm not as bad now though,i repaired a samsung 42" lcd tv the other day..2 caps in psu..10v-1000uf,105-Oc,

Please stop passing crap information along, even in jest (assuming you were really joking)

Electronics are complicated, there are some "simple" ways to explain it to regular people, but as shown, the OP has question upon question for each simplified answer.

A simple wiki search will yield some good info, most of it seems correct so if you, OP, want to know how something works, start reading here:

http://en.wikipedia.org/wiki/Capacitor

and

http://en.wikipedia.org/wiki/Resistor

Otherwise, stop spreading crap around with a fan.

wanted....posties with g s o h .....at your own risk Wink

Oh yeah! the capacitor be the culprits!!!!!

Keep the volume down when pushing the power on when no batts are in the Bboxes or they are not plugged to the out-lets!

Save/protect them speakers and all ICs!!!!

its probably bees in the transformer.

no its true, in the 1700's capacitors were made with what ever you could get your hands on, before maplins/radio shack existed you had to make your own.

Sorry for asking rather primitive questions.....That's just my style, I like to abuse people for info, instead of doing my own research Laugh Out Loud

I didn't do well in high school Electronics class........I don't even remember any of it at all. Laugh Out Loud I just enjoy boxes for their style & sound. The only maintenance I can confidently perform is spraying DeOxit. Laugh Out Loud Oh wait, I also greased a tape door once. Laugh Out Loud
