amigos,
ano ba ang dapat ayusin kapag ganun? minsan meron minsan wala. mahigpit naman ang kabit ng wires. sa ground kaya?
salamat po ;)
-
The potentiometer/Linear Taper also called (DACT volume control, or step volume control) is already busted. Electronics repair shop can change it.
Does your amp or receiver have remote control, is the unwanted sound still present even if you use the RC?
-
anong gear po yan?
-
if this is the round volume knob, sabi sa forums na gamitan daw ng deoxit spray (i haven't personally tried it yet)
-
baka makuha sa WD40 sir...
-
Yun sa akin WD40 lang nawala yung garalgal. ;D
-
wd40 is messy. use contact cleaner to spray the potentiometer while turning it several times. obviously you need to access the amp's internals to spray in the potentiometer's contact areas aka wipers.
-
I'm very interested to know if it's an int amp, or a preamp. And what brand of course.
-
hi,
i have the same problem.. sa akin naman int tube amp na fisher.. sa tubes kaya yun or sa potentiometer?
-
uy! ang daming replies. sorry, now lang nakaopen. it's dared mp5. minsan meron minsan wala. salamat po ;)
-
may dumi lang yan kayang kaya sa linis
-

maraming salamat amigo. ;)
-
may pagkakataon na DC ang cause niyan pero like they say, linis daw muna...
-
okidoks. linisin ko muna. kung hindi lang basta dumi ang cause, ok lang bang pabayaan ko nang ganun at di naman lalala o walang madadamay na parts? ;)
-
My subs volume control had the same problem. I replaced the potentiometer, it was a 20 peso part :-). mas mahal pa yung contact cleaner hehehe

i like the "potentiometer" answers... hehehehe.. sobrang techie ang dating...
napuno lang ng carbon yun...
actually... you can clean it by pressing it clockwise and counterclockwise very often fast then slow
but of course with the POWER OFF para walang effect sa VOLUME...
para lang malinis yung mga contacts nung "potentiometer"...
hmmm... brings back the good old college days... electronics engineering 101
-
sobrang techie na pala ang potentiometer... ;D

sobrang techie na pala ang potentiometer... ;D
variable voltage divider na lang sir... ;D
-
aliw talaga kayong mga masters ;) :)

Mga Amateur !!!
Metalic Electrical appliance displacement device marunong ka gumawa ???
AKA Extension Cord bwahahahaha
variable voltage divider na lang sir... ;D

o sya, lagyan natin ng dibuho:

gusto ko nga yun sir... at least not the ordinary everyday linggo...
i have not heard that term in a long while... =)
ang cute :D

mahirap yata maghanap ng electromechanical prongs, insulated extruded metal conductors at multi-receptacle bladed connectors para dyan.

bro Eric, agree ako kay sir markcrenz ...the oil residue might cause resistance of some sort kaya contact cleaner na lang siguro.. if your potentiometer (c/o Master J: variable voltage divider ;D) has large opening (upper area and underneath) pwede din lighter fluid.. dripping fluid will carry downwards the carbon/dirt... just be sure you have absorbent cloth or tissue paper underneath so that dirty fluid will not touch other parts.. lighter fluid evaporates kaya usually walang residue ..btw, do not light a cigarette, baka masunog yung amp ;D
cheers !!!

Barbecue Amp ;D ;D ;D
Btw, don't use those Mckenick sprays (WD40 clones), namuti yun plastic parts nun amp na ginamitan niyan sir... :(

ok, noted. though wd40 din ang gamit ko. ang husay sa mga kinalawang na na threaded anik-aniks. ;)

kung minsan o madalas, ang simpleng bagay ay nagmumukhang mahirap o complicated para sa iba and we often say, "ay, ganun lang pala yun!" kaya maganda na matuto tayong magtanong para matuto at ganun din naman ang magturo para sa mga gustong matuto. ibang klase itong PDVD! kumbaga kung may Google may PDVD! oh ha!

at may Hot or Not thread pa! :P
