Was in JP this morning and bought these two casings, for some other projects but quite suitable for the T-Amp.
Sold by NIXIE, first casing will costs RM28.00 while the second one finished in gun metal grey color costs RM46.60. No discount tongue.gif

Y.C.,
Looking good! thumbup.gif
Yeah.. those speaker binding posts may be a wee bit too close but if you're using banana plugs(are you?), I think they should be okay! wink.gif
The T-Amp is well protected against short circuit but then again, 'prevention is better than cure!' laugh.gif

P/S, I simply wish your pix can be sharper/clearer tongue.gif

Y.C.,
I have never seen a Deltron screw-on plugs.. where do you get them?
Do they look like this?(attached pix)

.. time to get a 'new' cybershot? tongue.gif

Thanks for the 'secrets' wink.gif Will make a note!

And my completed buffer pre-amp... sweat.gif
Now sitting 'pretty' on top of the T-Amp.. wink.gif

Bro March..
You're beginning to 'read' my style, eh? wink.gif.. there are reasons for the 'bareness'..wink.gif

Future expansion to include a VSPS board..Very Simple Phono Stage or a Phonoclone ( I still have a TT to cater to..) wink.gif
Backup power supply/battery charger circuits.. I am beginning to like DC power! thumbup.gif
Digital/electronic volume control.. to name but a few ideas I'm 'toying' with...
May look into powering the T-Amp by battery too! brows.gif

By the way, there is absolutely no hiss at max vol. The background is dark.. very dark.. Playing vocals at night give you 'goose bumps'..

Now working on a second buffer board.. Version 2 brows.gif

You're getting the TA2024 too? Serious? rclxm9.gif Welcome to the CLUB!!!! thumbup.gif

P/S

They VSPS/Phonoclone may look like this... biggrin.gif


QUOTE(March05 @ Nov 10 2008, 06:48 PM)
Oh Jazzy bro, you're right! It really looks er...bare.

Okay, okay,  I know lah. You like plenty of room to work in.  nod.gif  And enough space for future addons.  thumbup.gif Like that active X-over, perhaps?

Yippee, I'll be getting my very own TA2024 to play with tomorrow .  flex.gif

Thank you Y.C.,
In fact moments ago,I have just finished installing a power switch and a white LED at the volume knob to indicate power on. wink.gif

You're taking a 2 months break? Giving time for the blister to heal? laugh.gif Just joking!! tongue.gif

Anyway, congrats! Your 1st.T-Amp is finally completed! Pretty good looking on the inside. Too bad you're gonna cover it up... Will this be used at your office or at home?


QUOTE(Y.C. @ Nov 10 2008, 10:54 PM)
Nice pre-amp, Jazzy.

And welcome to the TA2024 T-amp Club, March

One last picture (internal) of my 1st T-amp duly completed. I am putting away my tools now; my Rosewood jewellery box (casing), 3rd T-amp board which I already replaced some of the SMDs with discrete capacitors and resistors could wait. No more T-amp modding for at least the next 2 months.

bsl,
thanks for the input but I'll find out if it is really 'very simple'! laugh.gif
just 'gatal tangan' want to do a PS. There are other so called simple circuits using some opamps like the infamous 5532s.. pix below. See lah if I have the 'mood' after this.
The T-Amp setup seems very well suited with CD based music. Am wondering how a TT would sounds like.


QUOTE(bsl555 @ Nov 10 2008, 11:07 PM)
Not really THAT VSPS (very simple PS)!..unless you buy all the ready made main components and fit it all up together...thats the simple part of the project.  biggrin.gif
Actually some so called hi-end PS don't even come near it and moreover command a rediculously high price tag.
Split the PSU and phono stage to a 2 box design and it'll command even higher price tag.

xtorm,
infact the board can be made even smaller! BTW, the working voltage of the JFET can be higher! So I don't see any problem with 12V... want to use in the car, huh? tongue.gif


QUOTE(xtorm @ Nov 11 2008, 09:20 AM)
hmm today seems to be free tho...haha

the buffer preamp is tht small huh!! can it be use with 12v? i guess no, any other buffer pre-amp using 12v? i think it will be easier tht way

Dybre,
This is NOT a DAC (Digital Analogue Converter). The TA2024 is a digital hybrid amplifier, a class T as Tripath, the manufacturer calls it. A Class D for the others. If you were to read (I know its too darn long), the board came pre-assembled just requiring few external parts and connections to make it work.


Added on November 11, 2008, 1:29 pmY.C.,
Thanks for the 'update' and I can understand the situation. Take a break bro.. guess you need it! laugh.gif

On my side I just will continue on with what I already had and planned, and will drop in and update the thread as and when is necessary. Honestly I have never put in so much effort in an amp! Also I am not bothered to count how much I have spent in the project.. What matter most is the enjoyment and excitement that I had while building the amp, meeting and getting to know you guys.. and sharing the pleasures of the T-Amp sonics together.. thumbup.gif

Y.C.,
Thanks for the link! Nothing new to us anyway.. wink.gif
If it is, then the T-Amp is one heck of a 'car stereo amplifier',right? brows.gif
Certainly put to shame many hifi amps many times the price laugh.gif

For what it is worth, what ever amount of $$$ that I put in, there were no regrets. It is worth every sen, effort and lost sleep that I invested in return for the fun, pleasure, experience and the sound that I finally have. I certainly went overboard with the casing! tongue.gif It deserved to be properly housed to reflect the SQ that it is producing. So good that I have retired my two Technics amps in favour of the T-Amps thumbup.gif
No, the Technics are not for sale wink.gif

bro March,
You can take a minimalist approach if you want to keep the cost down. Simple/plastic casings are available from JP. I did use that temporarily for my buffer pre-amp although I did plan to use the same casing for the pre-amp biggrin.gif It all depends on my final configuration as I earlier stated on my pre-amp plans..
Come to think of it, I have a discrete amp mounted on a plank! Is that bare or what! laugh.gif

I hate to see this thread coming to an end but its inevitable, right? Like they used to say, "All good things will come to an end.." Sooner or later...


Gnite all..

bro March,
Do keep us posted with your progress biggrin.gif Just a query here, will you be using a passive or active preamp with your TA2024?

xtorm,
A V2 would be timely as this is a rather long thread for the newbies, I agree! tongue.gif

BTW, would there be a 3rd. TT Session? hmm.gif

Monkey King,
Thanks for the post! Interesting stuffs you got there. You too have that F-ELNA eh? (fake ELNA)laugh.gif
I am using that F-ELNA as my input caps. Quite happy with it for the time being.. wink.gif
Welcome to the club! biggrin.gif

Yeah. Quality/reliability are the main issues with our local suppliers.. So far I have been lucky wink.gif
However I do have Vishay/ERO 2.2 uF caps which I will use before the F-ELNA starts to deterioriates.. wink.gif

That is after I have finish the on going projects associated with the T-Amp..
Do you mind sharing if it's T-Amp related?

Dybre,
If you were to do a little bit of reading the question will be unnecessary! You do not owned an Aego M no?
Aego M is a powered speaker system. It has it's own amplifier therefore no external amplifier is required to drive it. Comprende?!

QUOTE(Dybre @ Nov 13 2008, 03:23 AM)
could this be used to drive Aego M?

just a suggestion.
in the new version 2 thread(you better start soon!), maybe you should compile an FAQ to avoid this unnecessary 'not so clever' questions.. wink.gif



QUOTE(xtorm @ Nov 13 2008, 10:06 AM)
wow ta2024 driving dynaudio..tot they are hard to drive?

haha jazzy there are still some new comer, so ill start a new thread over the week end (my pc is down, using my gf bro pc on an off at night ), but wow 130 page in audiophile smile.gif hard to believe there only few of us tht are really doing the posting tongue.gif spamerkah laugh.gif

…answering them slowly will clear things up, some might just give up because it still sound complicated to them biggrin.gif

bro March,
I'd say it is but then again it is all depends on your personal preferences and what equipments you are having and driving tongue.gif
I have great success with 10uF EPCOS in my system although when driving your HB during the first TT Session, not much 'impact' was heard..
A 2.2 uF would be a starting figure and if you could afford it, experiment with the different electrolytics/dielectrics then the play around with the capacitance for 'fine tuning'

Yeah.. a 130 pages is wayyyy far too long! laugh.gif

QUOTE(March05 @ Nov 13 2008, 10:27 AM)
Is it general consensus that the Vishay 2.2uF is at the top of the list as replacement for the input caps?

Guys, I guess I can understand a bit of Dybre's confusion. This thread is too long! Even for me, it's hard going back through the 130 pages to pick up the relevant points. I'm eagerly waiting for xtorm to move to V2, with a nice summary of all the important stuff as the first thread.  biggrin.gif
