wui,
the Evaluation Board schematic is available at the beginning of the thread for download.

The datasheet for TA2024 is from my T-Amp stuffs folder<-- as earlier noticed by our Mr.Spy..

Here you go! For everyone to d/l too!

march,
Your T-Amp was truly plug n play .. and at a price too which I think it is not too bad!

We're having fun tweaking.. some people liked it, some don't.. I am enjoying every minute of it!

Oh ya... the T-Amp TT Session, earlier planned after Raya, have NOT decided on the venu although I vaguely remember, something about Y.C's place..

We have to wait until the gang have received the T-Amp (the fourth batch) and carried the necessary modifications.. I'd see mid to late october timing...

If you can bring along your TA2022 its even better. Want to hear diffrences if there are any... obviously there would be..

Certainly the end of a 'long' waiting period!
Good luck and have fun to the guys who will be modding the board!
Don't forget to update the thread with pix and your reviews...

desoldering sifu ongbs..

sorry bro.. I can't help it!

grandspy,
BOM not done yet... but that can be easily done with reference to the stage1/stage2 mod instructions, right? these past 2-3 days rasa 'malas' lah sikit... takder 'mood'..

xtorm,
selling the mundurf? WHY?

So, the input caps is purely a DC blocking cap function?
BTW xtorm, can you check the DC voltage at the input? I did.. you'd be surprised..

ongbs,
yes it is. I read it can be 2.5!
I think it was designed to be such a way..
adjust to zero.. hmm good idea.. time to re-look at the circuit

metalmania,
thanks for the tip for cleaning the tips..

Those stainless steel scrubs can get from this '2 ringgit' shop for exactly RM2 for 3 'heaps'.. cheap huh?

xtorm,
bro, what are u saying?
NOT a good idea to remove input caps? You damaged your mid driver because of that?
Ooopss sorry to hear that.. take it easy k.. like whay Y.C. was saying get a new one and life moves on...

Duly noted! Yup I have read the postings!

There are ALOT of speaker drivers in JP.. suit all/any budget. It's your call!

I think the term 'DC biased input' was mentioned earlier, right?

xtorm,
look at the bright side. we learn something new today, right?

ahh easy come easy go, huh? Thats fact of life

Yup.. thats about right.

BTW, how much improvement are we talking about with the input caps removal?

Louder I can accept.. dynamic? hmmm definitely will let you safely do it first!

At this point of time, I believe my T-Amp is at the peak of it's sonic performance. I'd rather not risk losing this level of sonic bliss..
I may use another board for the 'butchering' purposes but not this 'baby'

The only thing that is left and there are still room for it is the replacement of the stock inductors to toroid..

I believe that would be the final yard...

I have mentioned this earlier about the 'micro-surgery' done due to damaged C16 mounting pad..
I can assure you, this need a real steady hand and a very sharp eye...

Here's the pix of that 'procedure'...

Heyy good work there wui223!
Let it burn in slowly.. this weekend you can power up the full errr 9W?

Heyy your own DIY PSU eh? Lets see those pix eh?

Later can we expect a review on the sonic performance from you? TQ!

wui223,
its ok. suffice by telling us the details of the PSU.
What type of casing did you used? fabricated or bought ready made?

Actually 1A is more than sufficient to drive the T-Amp. I used 4.2A because of the anticipated bi-amping plans..
Have yet to accomplish that. Still enjoying the single amp ops.. Need to go to JP to get some goodies before the bi-amp become reality. Raya time I will be bi-amping!

Black metal casing from junkyard huh... interesting...

wui223,
I just remembered, LM7805 is for 5V regulation. for 12V you should be using LM7812. Am I right?
