ongbs,
when are you planning the mod job?
don't forget a post mod review k!
BTW, RIFA better than Vishays?

Whoa, my hats off to you, Ongbs. However, do see my comments above. 

Y.C.,
I was about to say that!
I am more willing to wait for Argen's next TA2024 board!

Whats the rush, right?
I mean, I got 4 boards! another 1 coming...

ongbs,
This so called new TA2024 board are being discussed at diyAudio.com forum.
At the moment, Argen is asking the users what do they want in this new board design having learned from the previous board.
Once he completed the design, he will post it for view and comments before producing it for sale..

here's the link :  diyAudio's link

new board design link here

What's your wishlist on the new TA2024 board?

Im impressed with you guys

Im planning to use use stock SMD parts, replacing only parts deemed necessary (have to read through this thread and refer to the evaluation datasheet) but nothing big ass like what bro jazzy buat, i prefer (if a must requirement) to replace with a better SMD counterpart to keep the size.

Decoupling caps, 6.8uF polypropylene capacitors direct wired to the board, power supply in the same box, toroidal 12V 24VA tranny > linear regulation > power opamp raw regulation to the T-AMP. Volume control, lowly over-stocked ALPS RK097, all packed into a medium sized Hammond extruded aluminium casing with the casing acting as the PSU heatsink. So a medium sized enclosure, with direct AC power and is able to accept both RCA and stereo 3.5mm input, selectable and output with pisang-plug.

Jazzy,
Do you suspect the Vishay 2.2uF capacitors are not actually Vishay capacitors in the first place? How do they sound in comparison to your Elna 2.2uF capacitors?  

Okay, my story of how I ended up as seller of Vishay 2.2uF capacitors is as follow: 
These capacitors need to be purchased in 5 pieces together at one go.
I was at RS Components on 02.09.2008 and was browsing through their catalogue and found these capacitors. They have been stated in their catalogue as Polypropylene Capacitors and are very suitable for use as coupling or input caps, hence I bought 5 pieces (ex-stock in KL then).

I only need 2 pieces for myself and thus was having 3 additional pieces to dispose off; so my mention in this thread.
They was a tussle for the 3 pieces as I only wanted to sell them off cheaply at RM9.50 each for the first 2 pieces and the 3rd odd piece at RM4.50 (with me paying RM9.30 each for the 2 pieces). I personally felt bad for letting down a friend after failing to supply him the 3 pieces which I had agreed to do so; I ordered another batch from RS Components which by then have sent their remaining stocks to Singapore.

All Vishay 2.2uF capacitors have been fully sold by me at RM8.50 per piece and the last 2 pieces to the friend whom I had let down for failing to suppy him the 3 pieces. I only collected RM7.50 each from him, much lower than what I actually paid to RS Components (I had given him a RM5 change in a single note instead of 3 RM1 notes as I did not have enough RM1 notes with me when we met up).

After having ordered from RS Components, I found out from the Farnell website that these Vishay 2.2uF capacitors are Polyester Capacitors and known as Vishay Roederstein. The RS Components website also state the same and are sold at RM42.10 for 5 pieces.
mysghooi,
Sorry, I no longer have any single piece of Vishay 2.2uF capacitors, not even for my second T-amp board which I'm going to perform the replacement of SMDs with Vishay BC capacitors and resistors like our T-amp sifu, Jazzy.  

Y.C.,
heyy mornin' there! You do come in late.. err early mornin'

Someone having a very sharp eyes noticed from my pix that the so called Vishay caps have ERO engraved on them.
A quick search found that they were Vishays after ERO has been acquired by Vishay.
....

hey there ongbs,
yeah.. at this hour it is always us! Those sleepyheads..

Say what caps are you getting? Vishays?
I presumed you have downloaded the Stage 2 instructions... any comments?

Anyway, happy hunting!

Mysghooi, thank you for sharing. 

I see that you could fit the speaker binding posts and RCA connectors to the wooden box; I am still having problem with mine. 

Any humming sound to your loudspeakers when no signal from the CD player is being fed into your T-amp?

bro,
Yes, my wooden box is made of Rosewood and it is both very thick and very hard, definitely much harder to work than metal box.

My T-amp is dead silent too with not a single hum nor buzz; I asked mysghooi so as he was complaining of buzzing sound from his two other amplifiers even when CD player is not playing any disc, remember?

......................

I thought so too after my change from the stocked input caps; but to me, the bass lines are better defined and I felt the balance of my Q Acoustics 1010 was restored with these caps.
I know, I know : "a man’s meat is another’s poison". 

I was looking at the picture of internal of Topping TP-10 Mk II and noticed the input caps used are Vishay MKT 1820 and their value printed as 3.6uF. The brand and its logo is also legibly printed on the caps whereas those I come across thus far tak ada. I am just curious as to whether caps got such value in the first place as I thought it should be either 2.2UF, 3.3uF, 4.7uF and so forth. Tiruan kot! 

bro ongbs,
you 'donuts' not tasting good, eh?

Y.C. haha posible

jazzy i haven downloaded the pdf yet, will do tht tonight but i think it should be great, so didnt bother really check it out yet , so no 3 is the best with all the smd cap replace? since the elna is now in, how it compare to just the input smd modded

ongbs, how much are those aircore? 10uh will be kinda big actually...duno those by diyparadise and trends are 10uh or not since they are kinda small...

I just found out from TA2024 datasheet, the Co caps to be 0.22uF for 8ohms load.. so the SMDs values was correct!
The 0.47uF is for 4 Ohms loads..

Minor mod coming up..

ongbs,
C5 and C17 are 1uF. NO, I did not.
C22, C25,C27,C28 should be the same value. 0.47uF or in our case 0.24uF

Added on September 22, 2008, 4:33 pmTo me it sounds great.
with the caps value changed, so will the the frequency of the filtering... how much? u can calculate. the formula is on the TA2024 datasheet.. hehe

ongbs,
Hehehe THAT’S good!
Are you just doing the right side only?

Wah, bro ongbs,
You only tell bro Jazzy alone only.
Can we also ask for poto mali to see your workmanship so far?     

Xtorm,
So when are you commencing your SMDs' replacement. BTW, approximately when is 4th shipment arriving?

Ongbs, no problemo. I was merely teasing you. 
Replacing SMDs with discreet capacitors without removing the input caps is kinda tough job as there is not much space on the board to work with; myself would sure find it a problem later. 
Postlah some pixs to set those of us who have not begun the SMDs replacement (me included) drooling. 

Jazzy, I don't have any grounding issue too.
A close friend of mine actually pulled a dedicated grounding line for his Audio setup (not because he has problem though) and the improvement was audibly superior in all areas - darker background, lower floor noise, subtle details became apparent, sweeting sounding, better definition to bass lines and etc..... 

Xtorm, fantastic news. 
I could begin my SMDs replacement soon just like bro Jazzy and bro Ongbs.

Y.C.,
This would be a 'cheaper' alternative to a power conditioner! 
I believe the improvements would be audible.. KIV this is my 'TO DO' stuffs.. (long list )

Agreed, without removing the stock input caps the Stage 1 would be a real challenge!  ongbs, you must have good soldering skills!

Eh, you're starting soon eh? Excellent! Waiting for your report..
