wui223,
I've already made one..

But thanx for the link.. gave me new 'ideas'..

Y.C.,
Did you managed to locate the shop or get one?
Yes. PM received and responded.

Great! Please revert with reports!! pix?

walau...apa pun mau gambar ah? bahaya woh

Jazzy,

This afternoon was too rush; ran a few errants nearby my office area and it's already too late to go KL, so going down to JP tomorrow instead. Xtorm told me you indicated the shop is near Nixie and he asked me to be on a lookout for a young and skinny Chinese girl and that's the shop.

Picked up my T-amps from xtorm this afternoon. Wow, the actual board is so small ya; don't know whether it got enough space for us to fit in those caps and resistors we ordered or not? And not forgetting the extreme care we need to exercise with the soldering iron.

Thanks for concern.

hehe...if snap naked model sure cun one, if dead stuffs like meter etc...hand sure shaky

btw, just search over SPMS in Ipoh, cap palang 12V 2.1A already cost RM68

wei, Y.C = Yam Cha ke???

Y.C.,
Now that you see physically the little marvel.. it's unbelievable, right?

When I was there, there were NO young skinny little gurl.. how come ah..?
Yes.. I use a pencil point adjustable soldering iron for that.. don't really like SMD stuffs.. and the board is double-layered!

Happy hunting tomorrow!!!

jazzy, have you measured the original inductors with your new shinning meter? in uH?

ongbs,
No I have not as I have NOT removed any of them, yet.
Will do that probably tomorrow. It should be 10uH, right?

pls measure it and "report" here
not sure it is my inductance meter problem or what...my meter read 5uH..

Ok, will do!
According to the evaluation board schematic, it's 10uH... no worries!

Y.C. is initial of my real name but it's not Yam Char. The last time you asked me same, I thought you were inviting me to yam char together.

Hahaha, I think it's more of symptom of my age slowly catching up with eyes straining to focus on close objects and hands not rock steady like my younger days. Naked, semi naked model or dead stuff, same sahaja lah!

I thought those smps which come with our notebooks are neater looking and could be hidden behind cabinets, will check them out tomorrow too. Would the sound quality of our T-amps through these smps be more inferior than through the unit Jazzy bought? Anyone?

Y.C.,
My earlier test using the SMPS is quite similar to the laptop/notebook type PSU. Housed in a black plastic casing, it can be placed outside, out of sight!
I have yet to compare, however the one that I bought is 'industrial grade' as ongbs put it..

Question is, can you get the black, good looking plastic SMPS as cheap?

Thanks, Jazzy.

Yes, the little marvel looks much bigger in pictures and considering this small little fella to reproduce fine sounding music, it's quite unbelievable. I thought the soldering job was a 'lil rough and not refined but for RM55, I guess it's no issue here.

Talking about soldering iron, I'll need one too as my made-in-China elchepo soldering iron was last used 5/6 years ago and it's now full of rust. Will buy a finer tip soldering iron just like you.

"Hahaha, I think it's more of symptom of my age slowly catching up with eyes straining to focus on close objects and hands not rock steady like my younger days. Naked, semi naked model or dead stuff, same sahaja lah!"
walau...sounds another "uncle" grade to me bro Y.C....welcome to "Uncle's Club"

Well, difficult to find 12V SPMS for lappy, most lappy voltage range from 15V to 20V.
If you could find one, it just works fine

Yet to test 1.5A SPMS as my T-amp lying on the "operation table', gonna replace 20k volume VR to 100k one, and change the coils to thicker wire one as well...stay tune!

Not at all Y.C.
I saw a fine great looking ANTEX going for RM55, a 25/30 watter. Will suit the job fine!
See attached pix. There is also an 18W version!
The HAKKO that I got is more expensive that that! It's a 20w/300W(pistol grip, push button for high temp application, ie the 300W).
May be later I can show you my really fine tipped soldering iron that uses 12VDC. Extremely suitable for SMD works..

Haha, thanks ongbs, as people usually say, "don't want to admit ownself old already also cannot".

I'll be on the lookout for one, and hope to be lucky.


When I was in Eunos, One-U last weekend, I saw one 'pistol-shaped' soldering iron with a fine tip selling for only RM19.90 and was contemplating buying it. Wow, RM55 is definitely much much above my budget considering I use it very little.

Thanks again.

Can i know where can i learn from? I meant about circuit.I want to get some basic theory for circuit design for AMP.

nice chat with Y.C. today, another experiance audiophiler...

hmmm beside nixie...if there isnt a young girl there then im not sure was it tht shop, there is a fluke shop there right? nixie is the shop just beisde the famous chicken rice right? or was i wrong...hahaha, sorry ah Y.C.

btw i think smpa are all the same, meanwell is very well known, no issues.

jazzy, 0.2ohm is nice!!! i think you should start calculating the cost to do 1 for use i wana get it but waiting for reports!! hahaha

ongbs knn you also got inductance meter? built in the fluke ah? must steal your fluke...hmmmm

btw cheapo soldering iron cant last, my cheapo rm12 unit when dead when i was modding my t-amp
