hi... after reading this mx5021 mod guide, I'm so tempted to try it out on my ancient acs45.1 & without much hesitation.. I did... mess it up >.<
the ori caps are
10KµF 25V X 1
1KµF 16V X 2
220µF 16V X 1
100µF 16V X 3
replaced by
pana TSHA:
22KµF 25V
pana FM:
2.2KµF 16V
470µF 16V
330µF 16V
stock opamps are 5 x ST's MC4558CN (googled, they're dual)
all replaced by national's LM4562NA
made sure (I think I did) all the solder points are properly connected... tested with multimeter... near to 0 ohm
after it's all done... when I switch on... the speaker make WOO WOOO noise as if it's in very high volume & the signal is disturbed... I cannot turn it off by pressing both volume buttons (this is how acs45.1's button works), the on/off indicating light is always on.. turn bright & dark everytime the volume button is pressed
I then tried to plug in audio jack & played some songs... nothing came out....
pics will be up in few hours... charging batteries now, any inference to be made based on just these? thanks in advance... any help will be greatly appreciated....
