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...!!
