nowadays altec cut cost give u china or taiwan rubbish inside cause they wanna compete with other cheap brands like edifire and sonic gera
so to solved that problem, simply just replace the subwoofer output capacitor, the samxon or capson to some better quality ones, if i'm not wrong the sub cap has the value 16v 220uf for those that run tda73XX. i think can use same trick for the yours
very big diff!!

hehe at least i tried to help solve the problem unlike MOST people here!
anyway worth a try! the original caps are replace on sight anyways =)

correct me if i am wrong =)

the stuff inside is almost the same as atp5 and can use parts from 4100 or mx5021
no shop in selangor area has parts for it unless he order online which is more aspensif... ban leong also not helpful
you can scrap for parts in those models above because usually its the amp,input or psu fry!!!

but if its tda73XX chip inside you van get parts from old car radio =)

the altec cut cost, common problem, it can be solved byreplacing a few caps demonstrated at jimmyauw. com
there is a guy here called 'pcworks' can help you fixit if you are lousy at the soldering iron
but the cost is another story =)

if you live around subang,just cart it over to my place and i'll do it for FERE!!! =)
no warranty =)

heh 911 is correct unfortunately =(
new models now cut cost put inside garbage
i still love my acs45.1

edifier one thing i dun like is the design and their spekers not as gud as AL, but AL now.....laubehnized oledi
haha too bad our garage sales section isn't as gud as it used to be, or else that guy can us teh tarik with the leftover money after shopping in garage sales
haih.... now the unscrupulous vendors are flooding the threats....vendors selling 'new' items should be placed in another thread
now the garage sales looks like DAM ALOT OF ALONG STICKERS feeling =(

YAY got sum1 call us sifu!! haha cheers 991=)

lol same problem again.... dead caps... the caps can open circuit di
same advice - follow jimmyauw com 's mod
somebody here called pcworks can do it for some money
or i can try to kill it for yo for free if you live in subang

i dunno what spoilty yet.... just have to open the stomach and see see poke poke
then just hantam whatever i have to replace teh dead ones

umm 2100....
the 4100 is below of it
my collection haha

heh my collection la!!
mx5021 almost the same stuff inside with 4100 and atp5
i was hoping to learn more because i don't have mx5021 in my collection

i also used cap ayamas before. see my richer friends boom boom their atp3 and shizos at that time....
go cycafe water saliva see them boom the acs45.1 T_T so sad

five years later then only i got almost ALL the sets i wanted buying garaj sales. some came faulty too
haha buy back all the toys you wanted when you were a kid =)

then, i realized that altec sucks when it is 'stock' non modidef (applies for old models only, new models suck no matter how you mod)
after recapping with more nicer caps then i appreciate altec because it sounds gooder
if only the original stock comes with the more nicer things inside

btw, nothing different in the first batch atp3 and the newer ones....
i noticed that the caps they use in oledr altecs are all same brand, but in newer ones all random brand at random places even same model
i saw this in used atp3 in cycafe about to bankrap
is just placebo i thinking you

only stock vs4121(accident type inside 4212 earlier lol) and above the production date use 7377, atp3 all use 7375 go check if you don't believe...

is it no sound at all? or softer?
did your try playing with your sub volume control, any crackling sound? pusing pusing abit?
which end of your input connector makes that problem when you play play it?

err.. i'm thinking you should try to clean your 3.5 both end. file it with an emery board/sandppr, wipe with wet cloth

or if the wires internally broke, due to twisting and stacking, just replace it

if this doesn't work.. then maybe the solder is dry, i've seen cases of this
lets open it up

thank you for proving me wrong =) so thats the difference lol

i got free food today =)

its not really worth the money to mod that model...parts might cost more than the spekers set
regular power filter caps oledi rm15 each, you need 4 etc.
unless you really wanna have fun diy, i'll tell you that 5021 cannot go far because the original speakers for the sub and sats not as good sounding in the first place (plastic cone) un natural sounding

Added on August 12, 2010, 4:27 pmits not as easy as you think just join wire
on the other hand i too need a kind soul to open the atp5 and 4100 volume controller because i only have the subs

please feel free to shoot me down if i am wrong:-

changing opamp alone will not really do much, bottle neck the sounds at other places eg. all the other caps
you heard jimmy auw's mod before? neither me. haha don't go jumping into conclusions change here and there at random places
you heard....the cheapest and best bang the buck talk
modding the crossover in the sats is quite stupid if you don't mod the rest to go along with it FIRST
and haha after modding your crossovers, watch your very lightweight satellites vibrate of your table
good? sure better than original. bang for buck? bang for luck!!!$$$

hmmn, my personal opionin is, mod all the signal path caps 50v 2.2uf,1uf,10uf etc. first before power filter
try not to change the original value in the signal path, because it will mess your frequency range later in the circuit
opamps are the last thing you want to mod if unsatisfactory because only then it will matter or at least can be heard the difference
if you are a basshead and don't give a damn about sq, just change the the signal path caps leading to sub amp chip no need for powerfilter cap mod yet until your next months pocket money received =)

and safety first =) if you decide to heed or not to.. you should.....
DISCHARGE power filter caps
be very careful with the soldering, unsoldering parts... the trace is like crap! destroys EXTREMELY easily
