update lng mga sis..na kita ko na ung problema...kulang pala ung isang supply na 32v galing sa transformer. Kaya cguro mag clicking ung relay, ung kinalikot ko na un na tuluyan na ayaw na mag up ung relay. Na check ko mababa pala...midyo negligence din on myside...kala ko kasi d nasisira ung winding ng transformer. Pwedi po ba ma rewind ung round transformer mga sis?

panu kaya sis na kulang yung 32? baka di balanse

ars · « **Reply #26 on:** February 15, 2012, 09:44:42 AM »

update lang mga sis sinuli kuna ung unit ok naman po...ang ginawa ko ung 32v na ok galing transfo ung ang kinabit ko dun sa supply patungo ng relay, tapos ung 32v na 8v nalang un ga ginamit ko sa kabila.

d ko ma explain masyado...cguro na meet naman ung requirements ng power amp kaya uma-andar sya...

salamat sa tulong mga sis...gob bless sa lahat

sis can you give us further details like : paano nangyari, may sound ba sa speaker, totally wala talagang sound, nagcliclick yung relay, etc. kindly emphasize the problem
guess ko shorted transistor yan (guess ko lang ha!)

nung nagpplay cya bigla nlang nawala yung tunog sa left..akala ko nga yung connector ko galing sa plyer ang sira, di naman..yung sa speaker selector A, B, A+B ay kinonect kona yun.. bali direct nah...kasi nasira umg POT...at yung balance naman nah POT, kapag tinudo ko sa left lahat, andon parin ung tunog sa Right..kapag tinudo ko naman sa Right, may tunog sa Right parang sirang tweeter at ang left wla talagang tunog...pinalitan kona ung POT sa balance, ganun parin wlang nangyari... ung sa relay nag ccheck nman xa kapag nka ON.

may na kita papu ako, ung dalawang capacitor ung malaki filter ata tawag dun (if i not wrong) hndi nah masyadong flat. at ung katabi nya na dalawng malaking resistor, ung kulay green 202 ohms ata un, ung isa umiinit... di nman sunog umiinit lng talaga kapag ngpplay sya... yan ang na notice ko sa amp ko de ko alam kong saan ung sira...pinagawa ko na to, isang araw ko lng na use, don ulit sakit nya, mahal panamn pagawa ko. parang niluko lng ako..

yung palang load ko ay 4 ohms bawat channel ...pasinsya nga pala sa tagalog ko di angkop,mindanao po me mga master...thnx ulit
