No wonderlah ongbs not impressed!

yes yes. I was aware with what ongbs has done..
I will look into this when I have the time.. definitely!

The 330uF caps WILL NOT be used..

Probably it's not worth the effort!
My PSU should be able to cope with any transient current drain.. I usually set the pre-amp volume around 9 o'clock position.
Now I only need at 8 o'clock position! Now clocking at 15 hours... and still clocking..

Okay, okay. Point taken.. the higher the value of the caps, the better! Will be in the checklist! Thanks for the advice!

gabanyayaya/guys,
received a quotation of EUR98/unit for the Class D amp!
Do not know how much the shipping costs.. he will revert.
What you guys think?

Note: This is a 300W+300W into 8 ohm

Exactly! Value for money? I think NOT

BTW, I have clocked 25 hours on the T-Amp (Set 2)..
Have not heard anymore sonic improvements in this 'lil marvel.
I guess 20 hours should be the minimum.. Someone said 100 hours! Too long way to go/wait!
I don't have that patience...

Y.C.,
I pretty much agree to that..
I should hit the 30 hours shortly.. will be scrutinising the sonics tonite
Just got a call from two TT fans calling me to join them in JP before they wallop lock stock and barrel!
Hopefully I can.. Anybody? TT Session in JP?

mysghooi,
hard to say without actually hearing it. Will your speaker sounds otherwise when connected to other amp?

Your T-Amp clipping?

This is not normal la for a speaker to be 'hissing' without any signal, it's like the amp volume at 'maximum' and treble set at 'maximum' too...
Something wrong with your amp?

That Class D amp no longer qualifies for 'best value for money'; so won't be taking that option!
That TT session tak jadi.. raining!

Alternatives to what? As far as I am concerned, TA2024 is THE ONE!

Now already hit 33 hours of burn in The T-Amp is singing beautifully now...

Looks like 'heaven' to me!
Which one of the beauties is your pick?

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

Power/quality/cost wise the GC is a good choice. Balanced.
I got ALL parts including the LM3886 chip from JP!
This is a while back, I'd say for parts alone, its between RM50-60. Power supply is another ball game ya!

You've been doing homework and research ya!

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..

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!
This is the best I could explain to you.

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!

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!

Heyy! That homemade toroid is a toroid inductor NOT a tranny!

hahaha this place is quiet la without you!

Most of my stuffs.. DIY stuffs included are normally black and shades of it.. kinda 'dull' huh?

This time, the 'flashy' chrome finish will definitely reflects the amp high fidelity, quality and 'out of this world' sound!
(pun intended)

Heck, may be I make a second one black with 'satin' finish!
I'm gonna have four boards anyway!

Just noticed, I just hit and exceeded the 2000th postings!

Sorry to disappoint you gabanyayaya...

Well, the basic T-Amp is singing sweetly now.. Diana Krall is playing infront of me here.. Simply couldn't locate my speakers!

RTL3, excellent speakers! They don't make these type of speakers anymore.. too bad...

The chrome thingy is done using electroplating method. Dip the required part in a 'chrome bath', connect it to one of the electrodes and switch ON for some time. Voila! Chrome plating!

Yes I ordered another 2 boards!

ongbs,
this is no paint job!

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."
