Fresh out of the wrapping paper, I hock up the t-amp to my 6ohm bookshelves speaker and tap on 12V power supply from a spoiled china made DVD player (use that as housing also). My impression is, this little thing can sing, it is clear and crispy. I hock-up my car line driver to it and it sound damn loud and smooth. By the way I haven't mode anything yet.
My plan will be change some capacitors as everyone else did and build a simple line driver (I think something like C-Moy is good enough) for it.

hi all, may i know what cables you use for the tamp internal cables? that connect to volume pot, RCA jacks etc...?

DIY braided CAT5 or just any generic cable as long as it thick enough?

thanks

I use a 'normal' 30A electrical cable for speaker output except the input uses shielded stereo cable.

I would offer "To Each Their Own" as answer.

I am only using the RM0.30 per metre run of AWG-26 multistrands copper wires for internal wiring throughout. Read about my thoughts and rationale behind some of the actions in building my T-amp: Summary of T-amp project, most if not entirely all were expressed in this thread before.

There are several links to some very interesting sites in my said article which is updated from time to time.

I'm starting to get used to JP quality. Today I was soldering a toggle switch and the terminal came off even when I solder for less than 2sec! It is so much different when I shop for components there during my college time..

I saw a casing at Nixie...smaller than yours but I guess it should make to look like a decent amp for me to put in the living room

Added on November 18, 2008, 9:41 pmIn my CDP, I use silver cable for signal Anyway in t-amp, small signal, I use screen cable. speaker and power cable will be 26AWG. IMO, keep the signal cable as short as possible.

Acquiring amplifier chassis seems to be an eternal problem eversince 3 decades ago. Yep, you can get small boxes and only lately, extruded aluminum boxes for small projects. Thats why I had to stand on my head to get my tube amp chassis customed, but at a great price I can't get again. This is also one primary reason I'll not build any SS amp in future. I prefer and expect my own personal desired components acquired easily, no half past six work or a any old chassis for the sake of having one.

Oh, back on audio taper/control/pot, always go for LOG pot, not LINEAR pot since audio is logarithmic dB, a 15dB signal is TWICE louder than a 12dB signal. A linear pot would make the volume sweep exponentially.

Ijan. The trouble is, LOG pots are not easily available at any Jalan Pasar 7-11. You get B types galore. You ask for A Log pots, the counter girl looks at you and think you're speaking French.
Anyway, I've always kept an Alps Blue 100K housed in a small extruded aluminum box as a passive pre standby for whatever personal purpose.

Th thread gets quiet again here is some pics of my T-amp case, I lost the backpanel, I don't know whether I or Senior loses it, but finally I found a way, just drill the top and put the speaker terminal there


The innards, nothing special

you don't got any troubles with those cheap binding post that senior bought to you....????

and i see d'dac......strip naked....how does it sounds without input cap with the t-amp???

Trouble? What trouble? It works just fine

Its not input cap its output caps Without it it sounded more detail, maybe a bit dry but I liked it. But because this T-Amp only have passive volume pots, it sounded too dry, maybe I wanted senior DIY buffer now

gabanyayaya,
that binding posts probably not the same 'elcheapo' ones that you bought! This one very sturdy! Mine also cheapo but better...

Input cap...output cap....ahh...they just the same as long as they're capacitor.....


all you need is just to ask.....wonder if senior could consider handing his favorite toy now to junior....????


jazzy you need to help me get this binding post la.....last time i got back luck. all of them just break and patah.....!!!!

sometime we need some help from those who have been blessed with the angel of hifi lah...

gabanyayaya,
I need a few pairs of those too for up n coming projects. Will keep a pair or two for you.. Unless you want the 'gold' plated one like Y.C.'s which you know where to get, I am getting mine from this particular shop.. as the others are.. not good enough for me eventhough the price is similar, the quality is not. Such is JP's products... We all know that by now, right?

I will only handover that buffer when I have a better replacement! Which is coming up next!

tomorrow ill setup version 2 sorry for the delay, at the moment i got no order to work tomorrow...argh...no income then

i haven get my mobo back yet, but probably ill be all alone tomorrow to get V2 going and my pari of tannoy fix properly

Before this thread closed,i have one question about thump noise.

Recently, i have thump noise when switch off. But last night after i replace the input cap to F-Elna type 4.7uF, i have switch on thump noise. So whenever i switch on or off the t-amp, loud noise could be heard even volume pot turned to minimum.

Any remedy?

Speaker output relay like what Jazzy have done. Most AV amps have these relays (including speaker protection circuit) fitted as standard.

Guess this would be the final resort or i gotta live with it. Btw, is another TT session coming?

Yep!.. I wouldn't want to hear pop, pop de pop de thump at 7 AV speakers.

version 2 is up

ill close this thread, any good suggestion to the new thread please voice it out at V2
