WHAT FUSE IS USED IN THIS SUB


The fuse is external, mounted on the back. I think it also holds a spare fuse. Rating is marked next to the fuse holder.

I HAVE ONE MOTHER BOARD MS--639O VER:30B AND


HP motherboards are made by a motherboard manufacturer, for HP.

Typically Asus and Foxconn.

These manufacturers are the only ones, that would have direct values given for components used on that motherboard.

For example such as the capacitor's coded c212, and c209. (Code stamped on the motherboard next to the component)

Same thing with resistor's r9, r10, r12, and r13. However, the value should be coded on those resistors, just like any resistor. Use the color bands.

http://www.csgnetwork.com/resistcolcalc.html

A lot of times Electrolytic Capacitors that are of cheap quality, are not marked except for a manufacturer code marking. By the Electrolytic Capacitor manufacturer.

You may, or may not have luck in finding what that manufacturers code is.
First thing you need to find is what manufacturer it is.

Generally, manufacturers use a symbol for their name. Sometimes they stamp their name. Example Sanyo.
From there you can find out the needed information.
I believe the following article may help you in your endeavor,

http://www.hardwaresecrets.com/article/595/2

(The above is Page 2. You may wish to start at the beginning of the article, also.

At the bottom of the written text, you'll see 1, 2, 3, and 4 in blue for the page numbers)

You can also tell me what you see on those capacitors, and I'll try to help identify them, and their values.
Just post this information in a Comment.

My son and I both own Infinity BU-120 subwoofers, and both exhibit the same problem. Fuse is blown, and the C6 capacitor is blown apart -- literally. I was told to replace that capacitor with a 10mfd,...


Msullivan56 & son,

Yes indeed... We are on luck...

There are circuit board layout drawings...
on my Favorite FREE "manual" site ...
starting on page 20
(SHOWING POLARITY)...

Plz click here...

Infinity BU 120 Service Manual Amplifier subwoofer Bu 120 hts

Hope this helps...

My First "experience" of getting soot embedded in my SAFETY GLASSES... WAS PLACING OF A MODERATE SIZED
"POLAR" filter capacitor in a pretty large RECTIFIER PANEL...

I HAD FOLLOWED the Circuit Drawing ...
(arguably correctly)
as there was very little of it left)) when
POWER WAS RESTORED ... (sort of)

I came out of the EXPERIENCE WITH AN ENDURING
respect for SAFETY GLASSES... looking rather
like a Raccoon (I'm just saying).

Wear them...!!

Infinity BU-150 has deep hum soon as plugged in


most likely it's your signal cable. You might first try plugging the sub into the same power outlet as the preamplifier, if it is not already.

Good luck,
