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

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?

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

ENEMY SPOTTED!

reflow the dry soldah there!!!
the output from your 7370b is loooooooooooose
while you are at it, reflow the rest circled too for insurance =)
it looks similar to 4100 inside but unfortunately i am not much of a help =(
this place has a better idea for you http://duskblue616.pixnet.net/blog/post/14507867
looks like you'll need a major recap for the all the caps inside is lausy make in taiwan/china
as usual my idea of mod always starts at recapping the signal path first, powerfilter 2nd last and opamps last
cables and interconnects optional =) unless faulty

also, if you manage to get your hands on 50v 2.2uf elna,nichicon audio grade caps, and around selangor area i wanna bulk with yoo =)
because when i change the value, the sounds kelong

are you sure you used the correct/still good condition components? you shouldn't get pak pak and slow tweets if good mod
if using 2nd hand components no need to burn/run in. should be good to go

cs21 =)
not much ppl own that model....

hehe went to klang at lunch break stumbled across

what a great way to spend my saturday

didn't get to finish my recap cause i got a new toy to recap

yay! almost done now

anyone got any idea on replacing that thorn? 16v 0.1uf?
i got nothing that value.... what to replace it with?

hello everyone! today, i bought some goodies =)
ADA885 sub only
and ACS495 sub only

bukak time!
anyone got the fullset wanna share the rest of the circuit i'm missing?

hmmnn yeah i noticed the same thing for the ada305@acs495
new toys =)

ada 885 got double amp... one inside and one outside.... the one outside is cooled by the bass tube... the sub one inside as pictured above gets minimal cooling, which can get hot fast.... adding a fan is useless in this case... probably changing the the heatsinks to larger copper plates works better
then again at the end of the day... too much work/$ involved unless you want to fully overhaul your treasurebox

hey guys =) have you tried plugging it into another source? it might be your tv for all you know?

my guess is....
if it comes from pc fair it should be old stock or slightly defective product
my best guess is that 1 or more (plik plak suond)signal path capacitor is dead, hissing sound most likely come from power filter cap, so changing/upgrading it will be a good idea... dry solder might also be present in such situation
if i wouldn't ask for help here if i am no good with a solder and don't know how to pull your set apart... and most importantly we all need pictures of the insides before guess work =)
try your warranty first before attempting to cure it yourself unless you super confident =)
