e check mo yung selector sw. kung saan ka nag lagay ng input sa likod, kung tuner ang input mo dapat nasa tuner din ang selector mo, or baka wala kang wire sa input/ output ng equalizer in/out sa likod ng amp mo.

mga paps and gurus... parang may sabit na yung volt pot(potentiometer)
ng konzert av-502a ko eh... hindi na makuha sa linis so baka may diperensya na...
nababasa ko sa ibang forum na isa nga ito sa sakit ng 502a kaya minsan late,
mahina, or may black/blank spot either sa left or right channel ng speakers...

may nakaka-alam ba kung anong volt pot nitong konzert... papalitan ko na lang..
at meron din bang good replacement dito na mas maganda kesa sa default parts...
specific parts/number/brand po sana... TIA!!  ^_^

Sis woots,

tanong lang, ano ba ang value ng tone control's potentiometers? at bakit may parang glue ayun sa pics mo?

ganito kasi ang amps ng videoke machine ko. nabali yung shaft ng base tone control pots. siguro lasheng ang nag-adjust, nabali. hehehe ;D ;D ;D working pa naman, pero gusto ko nang palitan. pero nakakatamad magbukas. gusto ko bumili muna ng parts.

salamat.

:)
