Sorry to cut in...

I'm still using an AL ACS 45.1 ( using for probably 10 years I think ) ...Left & Right speakers no issues, but the subwoofers sometimes no sound and sometimes have sound... then I adjust the line in connectors, again, sometimes got subwoofer sound, most of the time... no sound.. errr.. I dun think anything spoil but probably loose connectors or the low freq volume control faulty or something...

Would you be able to help me repair it... ??

I still like this speakers compared to the newer ones... like everyone says.. the new ones quality very bad la...

Thanks

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

what abaot this..

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

no, problem bro..

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

i heard changing the opamp is the cheapest and best bang for the buck mod...
plan to change power filter cap and opamp and some crossover mod only....

Jimmy Auw did some mod and according to him its quite good
plan to do the same thing...

---

Added on August 12, 2010, 6:11 pmif it cost alot then i'll just mod the sub and opamp to deliver more tight punch.
i'll be using my sennheiser HD280 pro for mid and treble, the 280 pro is kinda lack in bass so i stack it up with my MX5021

playing both of them in parallel

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

if i were to mod it, i gonna change the fitering first before changing the opamp la... atlease easier to detect if something went wrong...

and no im not gonna make my satellite shake my table... im focusing on the bass driver now... think of ditching the satellite mod (for now) coz its gonna cost alot and furtile if the source that feed the satelite isnt good


this is what i had in my mind too... change the signal path caps leading to sub amp chip, powerfilter cap and opamp for bass unit
oh btw, is it good to change opamp for the sub at such early stage ?

coz im gonna use my sennheiser headphone to drive mid and treable...

This post has been edited by general_odin: Aug 12 2010, 06:54 PM

heh in that case... you can just change ONLY the caps in the signal path towards teh sub amp chip
stock 4558 good enough. no need to change opamp because you ditched your sats, you will not hear anything?
powerfilter? naw... you don't need it... the original will do.... go look at the price of the signal path caps first
if you want to change the paria 'maxcaps' or caps like that, forget it... duneed to mod lah =)

headphones?? roflt you gonna use the sub just for vibrator? hahahaha ok still your choise hahah hahaaa =DDDd

actually, if you are super noobs like me.
i will, open sub count how many caps of what value write on a paper....
then... i go check the price online first befoe i go thinking about modding
befcause if you m'sian, you will spend more than 50% of the modding time looking for parts than modding it

totally agree... finding parts is hectic here.
im gonna use it to vibrate my table and stuff... also add more bass to my headphone... im still gonna use the sats but i have headphone over my head so i wont be able to listen to anything that come out from my sats.

gonna save up around a few hundret bucks and start my modding sometimes soon XD

Thanks for the advise.

Attached thumbnail(s)

hehe np, i love modding anything altec anyways =)
good luck modding your stuff and show us your mods! i wanna see oso

its digital controls version?
wow thanks for tracing the outputs!
do you have ideas on 4100 and atp5?

Sorry for the slow reply...

It is either no subwoofer sound at all or have subwoofer sound, sometimes I hv to play heavy bass sounds to kick the low freq sound in..

these days, totally no subwoofer sound... satellite speakers no issues at all ( of coz sometimes the on / off switch a but malfunction but not an issue ... )

sub volume control... turn to extreme right, middle or extreme left...also no sound.. no cracking sound...

I did change to another working 3.5mm cables.. or plug to other sound source to eliminate the cable issue.. both cables is clean and nice...


When you mentioned solder is dry, what do you mean ? How to check it ? Which parts to check for this ??

Thanks for helping...

no saund??? O_O habis la got burn smell anots? smell the bass hole and see
hard to identify your poroblem di now, too many possibilities. unless you opem the sub inside and take picture both sides i cannot really halp yoo


solder dry means the solder inside old di tercabut lo because vibrate by bass saund
if not is broken trace also common poroblem isnside the altecs
open and check for burn marks first?!! then watch for pregnant caps and see the trace side for boroken trace or dry soldah

Ok, here are the pics on both sides of the board...

I did not smell burnt stuff... most probably loose connections or dry solder..

What do you mean broken trace ??

Nowdays, only stereo sound.... no subwoofer sound at all...

Thanks
