What jazzy change is the input caps. For input caps generally there is few things that should be considered:

1) Its best to use non-polar caps, or better non electrolytic caps. It is best to use non polar caps here if its electrolytic, and best to use non electrolytic (film caps, like polypropylene, polyester, or its metallised variant) but there is some good electrolytic caps like non polar Rubycon Blackgate NX HQ that is suitable for circuit that carrying audio (like input caps)

2) The capacitance: Best to stick with stock value, but if you want more bass, try a higher capacitance. Like jazzy change to 10uF from stock 2uF, it improves bass response considerably

That is based on my experience and my knowledge. Perhaps a more veteran and hardcore modder like empire23, LittleGhost or Ijan can give more info regarding this

T-Amp driving headphones? Its a big NO. Read here

Altec Lansing already have amplifier build in inside them, you need to remove it first to use this. If you don't know what am I saying or how to do it, you better stay away....or do some reading first

Yeah, you can use any passive speaker to use with this. PC speaker already have amplifier build in, so don't do double amplification

I'll have my own T-Amp soon. Maybe after he finishes his modding than he can build me one, which he plan to use my PC PSU to power the T-Amp

Hmm...weird...no one ever done the review on yesterday's meet?

Should I write my reviews here too? Actually I can't hear at high volume, all I hear is noises inside my head, plus the small room bass is killing me actually, its resonate in my head

Well, not really sharp, but the treble sounds a bit harsh for my taste, not piercing, but harsh. But I satisfied with it, even at stock it sounds excellent, the stereo separation is just excellent, I don't need to focus myself to hear the details, plus I do hear a bit more than before and it sounds very clean too. Its a bit dry though, maybe because I don't connect my subwoofer yet. I shall say it does outperform mine...I mean Senior's Technics SU-V7 amp

I have some caps somewhere, I have ELNA (real one that is ) 470uF 25V, I think putting it to replace stock 220uF

Thanks Yeah I been reading a lot in this thread so I have some plans what to do on this amp, like the aforementioned 470uF tank caps and replacing SMD. But I think I skip the SMD part, as I have shaky hands and I tend to be notorious of destroying things

I done some more mods on the amp. Three stages of mods, but I can't post it earlier due to unreliable internet connection (thanks Screamyx) but I wrote it to WordPad

Initial mod, Senior replaced the stock input caps with his famous 2.2uF F.ELNA and his big 10,000uF caps on the power input. Initial testing reveals smoother vocal and treble, and a bit more bass without the uses of subwoofer, but too much 's' distortion (sibilance) on some female vocal at high volume, but it seems to have more weight on female vocal too. Sound are well balanced throughout the spectrum, a bit flat, but I liked it. But I think it can improve with time, as it burn in.

2nd mod, I paralled 180uF Sanyo OS-CON with stock 220uF on tank caps, it sound very harsh, I ditch it quickly, so don't use Sanyo OS-CON on this amp.

3rd mod, I paralled 220uF 16V Rubycon caps I take from my dead Prodigy HD2 and paralled them to stock 220uF, plus I take another 1,000uF and paralled it with 10,000uF on power input for tighter bass, and my final mod is I take the stock input caps, removed the harsh 1uF electrolytic and paralled the whatever-film-it-uses caps to F.ELNA 2.2uF (for a total of 3.2uF), now the vocal has been smoothed nicely and the sibilance ('s' distortion) is minimized, sound much sweeter. I now use subwoofer at this stage. The bass is too much for my liking at high volume, but its beneficial for gaming

Another mod I plan, is to use proper volume pots, the volume pot I use now is unbalanced, on certain volume its more to right, and to the left on others (its JP volume pots I think), and at the lowest volume, there is still sound leaking out of it.

What I particularly like about how T-Amp sound is it give the sense of 'space' all around, and the precision it 'displays' on instruments is amazing. I'll post some picture later. Currently, the amp has only run for about 17 hours, still in burn in stage

Thanks a lot Justblair! It would be more better if the picture is bigger though.

NO, this is used to drive speaker, not headphone

Do you have any clue what you talking about? Do some reading first, if you don't know what you're talking about you better stay away from it

A bit of update on my T-Amp. My final mod to it is I put two 3300uF high quality Rubycon MBZ in series (totalling 1650uF) on power input, I don't think I need the enormous 10000uF like Senior did. I even try several values of tank caps up to 690uF (470+220), finally I settled at 440uF (220uF stock paralled with 220uF Rubycon caps)

After it reaches 20-ish burn-in hour, it started to sound different a little bit. No longer harsh like before, its smooth the high a little bit. Even though my current amp is without buffer unlike Senior did, but I like it sound to be a bit dry, for me its better to be dry than been surrounded by bass since my room is small

Oh, I forgot, I powered my T-Amp with my computer PSU, all 33A continuous current available on 12V rail at my disposal It sounded great, with no noise whatsoever, except if I play games when the PSU is been loaded, but I minimize it with enabling Vsync (limiting framerate to vertical refresh rate of the monitor). Something on my graphic card generating that noise, most modern mid to high end cards develop that annoying noise when in 3D games

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

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
