element14.com is one. RSOnline is one, jalan pasar is one

thanks for the info, RS,element 14, jln pasar.. your answer is right .
however at jalan pasar there are lots of shop.. OK, i been there weekly...

so anyone here has experience the exect shop, as they commonly bought components.

to be exect.. im looking for STK 4048xi ics, which is not available in RS, element14 and jalan pasar as they said they run-out of stock..

so the other choice and idea is penang electronic shop, however i never been there for electronic component hunt. so anyone here from PENANG has the answer....

That is an expensive STK chip! See here:

Making a 'super-duper' amp?

yes...i'm not a modder which is change the little smd component and hair string jumper..
i focussed on high wattage and voltage amplifier.

the amplifier..

my previous project

Final Year Projects - 40V p-p

Hobby 1 TDA7294 - 80V p-p

Hobby2 TDA1558Q - DC12 V (embeded into my coolerpad + LCD tv speaker)


NEXT Project,
STK 412-170, Shift Power supply VL and VH

STK 4048xi, Single channel amplifier

Please, anyone here has same interest, pls share..
from DiY Audio, there're lot's but im looking for malaysia mate...

I have 'played' with STK chips and also owned a few audio units that uses STK chips.. They don't have to be 'high power' to enjoy the audio fidelity..
There are better applications if POWER is your interest. Any particular reason why an STK chip?

actually i would like to build and test the diference between the amplifier chip. tda i already done, and now investigating STK. just for a hobby and experience , i would like build STK based amplifier and play with it..

Understood.. having played with lots of diy-ed amps I get most satisfaction from discrete and STK based amps.. still the ultimate are tubes.. now I'm into tubes
Keep us posted with your experiments/journeys.. enjoy.

tubes is another one interest, tubes investigation maybe after STKs... just wondering where to get the tubes...

You can get some from local online dealers, forums and shops but the prices kinda 'steep' to me.
I get mine from ebay/online dealers like tubedepot etc. Those china kits for starting and experimenting are okay .. I started with diyparadise's 5687 preamp.. kinda cheap to start at below RM500...

Sifu-sifu...what is the best/cheap for first time DIY project for Headphone AMP with readily available components kit?
I know AMB labs Mini3 kits around RM200++ kits..
Any other options or choices?

Thanks

Many start from the 'basic' CMOY and move up from there..

i have a few STK and TDA if anyone intersted
i need to go dig

but no have STK 4048xi

Any chipamp kaki here?

Hi every sifu here,
I got one toroidal transformer the output is AC 0-12V + 0-12V 650mA, can i parallel the two AC 0-12V to get 1300mA ?
Because the both cable for each AC 0-12V are same color (blur blur and yellow yellow), that mean have no + - polarity for AC 12V to do combination right ?

may be can, but the parallelisation do after the rectification.. since the output of transfomer is sine wave. it may cancel off the waveform if both peak coincedence ... ...

Have you tried Nixie at Jalan Landak? =P adjacent to Jalan Pasar...

may be can

Base on my little knowledge, yes sure you can, better parallel the rectifier output. also can parallel the transformer output blur with blur, yellow with yellow. but base on my experience, this connection make the transformer produces more heat.

hehehe.... thanks for da info.....

here is my experience and some little knowledge of jalan pasar pudu, been there once every 1 or 2 weeks

Nixie = Lot of project , cytron, uContoller, components, enclusure, most project part are available and general component quite pricey

Online Components = Interesting project available including non ordinary components = Thermolelectric peltier, solar, gadget Li-ion battery

R.E Spares = Lots of spare part and mostly availble, velleman dealer and dare to quote higher price due to availablity. (my last choice of shop)(STk 4048xi available here)

Maplin = Generally like other component shop but here the heatsink cheaper, hobby kits

Darson = Cheapo china electronics product

Melectron = General electronic shop, spares not as much as R.E. , now having CCTV section in front. CT Brand, Pro's Kit, Hakko distributor

Magnumtronic = General elctronic shop, washing machine PCB spares, component as well

Standwell = General electronic shop, have older spares/ part/ also having torroidal transfomer

Meter Trading = General electronics shop, ics are cheaper. (most of my component i bought here)

K.E Electronics = General electronics shop, component are cheaper if bought in bulk like RM5 for 100pcs LED

"unknown shop" = in same row of Meter and KE, have higher amperes of regulator ics, LM78xx series 2,3 amp rather than normal 1 amp at other shop . They also provide repackaging laptop battery or custom battery pack.

and newly found a shop that can repair speaker, changing everything as long as you only have magnet and chassis (paper,cone,diaphram,coil replacemnt available)

ok, that some of experience at jalan pasar pudu. For those lowyat members family's or relative's shop are non listed in my list, pls serve better components and cheaper price and maintaining new/ lastest product in store...

and any one here have experience for jalan pasar part hunting?? kindly share...

*answering santik idea, i already went there and ask...
