At USD43.88? I can't say.. Not aware of LM3883RA performance.. tongue.gif
More expensive than the LM3886.. should be better! wink.gif
USD30? Really... well it's kinda close to what rsmalaysia is selling too!

IMHO TA2024 is a good kit considering for the cost and simplicity...but 9W is a bit power shy la...

for GC i think is a good choice...50W is fine. jazzy if i'm thinking for a point to point GC power amp, how much i have spend when sourcing parts locally like you did.....

Power/quality/cost wise the GC is a good choice. Balanced. biggrin.gif
I got ALL parts including the LM3886 chip from JP! wink.gif
This is a while back, I'd say for parts alone, its between RM50-60. Power supply is another ball game ya! tongue.gif
*
yup....power supply...base on your experience...how much it cost??? a simple decent power supply.....then compared to that snubbed thing......

You've been doing homework and research ya! tongue.gif

A normal good quality regulated PSU should suffice for the GC. At least, I'll start here first.
Last year it cost me around RM70. The bulk of the cost goes to the transformer! This year should be slightly more.. wink.gif

Snubberized PSU is the use of resistor and capacitor network to restore the sound when you have a difficult speakers to drive and by using bigger caps on the power supply, tends to rob away your mids and high ends. The snubber network is supposed to restore this! biggrin.gif
This is the best I could explain to you.  rolleyes.gif

Snubberized PSU also use expensive high speed diodes(MUR860 (RM6 each)) and huge main reservoir caps @10000uF.. not including the toroid!
A 2x30V 225VA can set you back RM154(rsmalaysia price). A 10000uF 40V cap will cost Rm34 while a 63V one is RM150! tongue.gif

Unless you have very hard to drive speakers, a non-snubberized PSU should be fine!

Did I satisfactorily answer your question? Sorry for the deviation guys!  blush.gif

hmmm.... RM60-50 for amp and RM100 for PSU is still ok I guess....and you said toroid can be home made hehehe....this could be big project here...... jazzy is always here biggrin.gif

Kit? What you mean?
It's just a plating done to any metal..normally we use steel.

Definition from wikipedia:
"Chrome plating is a technique of electroplating a thin layer of chromium onto a metal object. The chromed layer can be decorative, or it may help provide corrosion resistance."

As long as you're a fan.. why not? The more the merrier!  rclxms.gif

Honestly, the chroming is just on the 'drawing board'.. subject to time and $$$... tongue.gif

The main thing is the sound.. looks are secondary...  rolleyes.gif

mysghooi,
RM20? Whoa got some more? I think it's reasonable! biggrin.gif
Looks like it's made of aluminium alloy and some steel plates. Either anodized black or painted black.. Where did you get it?

Y.C.,
Thank you for accepting to be the host for our first T-Amp Fan Club gathering!  thumbup.gif  Shall we call the club TAFC? tongue.gif

Saturday is good! Maybe not lunch, what about a 'lil later than that? Afternoon tea? Around 1500 hrs?Just a suggestion.. tongue.gif

I normally warm up my stuffs too... with T-Amp, the chip is hardly warm..  maybe the input components need to be warmed up, yes? biggrin.gif

I'll bring along my T-Amp.. and every one else too, if they want. Then we can listen together...  wink.gif

Sounds like a good plan!  thumbup.gif
