good luck
It can be interesting to know "where" you found the bridge, since in many places a bridge could stop completely the amplifier, and this is not the case: do you remember where you found yours? Thanks anyway, since this is another good help after panomaniac's one!

Go back over the amp again looking for bad solder or solder bridges.

Can you get access to an oscilloscope? If you can, you will be able to see straight away if the bad channel is actually running.
Take the Speaker Voltage Test!

Unfortunately no oscilloscope. I will follow back again the line, trying to find the problem...

Hi niico,

I tried to send personal mail, but I'm too new in this forum so I'm under moderation,

Well, I've been reading about your experience with 6 amp building and it's very convincing. I must say that I'm in a very similar situation as you, I think:

1- Totally novice

2-right now I'm building my DIY fostex speakers,

3-I have not much time to do this tipe of work, I only have time on saturdays in the afternoon. Maybe it's plenty, but I don't know how long it takes to do this amp.

4-Then, I started to get involved with these mini amps, reading and reading reviews, and I came to DIY tripath amps.

5-Maybe I give up and buy a trends Audio, or get Lepai T, wich I've been asking allready to other collegues here in this site.

Well, the question it's not very origina?, but once again: How dificult you found soldering this amp?
If I decide to do so, do you mind me asking you any problem I would have (I hope not bodder much)

Cheers niico

To get the D amp experience, first buy a TA-10 - it sounds really good. Then get an Amp 6 Basic - easy to put together. I have them both and they are very similar. You could then work your way into more complicated 41Hz amps like the Amp 5.

Default Where to begin..

I recently completed an amp 6 Basic, using a 36watt, 12VDC SMPS to provide the power. I used decent quality RCA inputs and similar quality binding posts.

I encourage all who are interested to read a couple of articles that I've written about my experiences in Affordable$$Audio. I too am a "newbie" when it comes to amplifier kit construction. Taking the time to get or build a suitable enclosure seems to be the biggest hastle (I am in awe of those who complete projects like this , and then house them in professional-looking enclosures).

My only true "issue" was the sacrifice of a Tripath chip, because I simply did not look at the chip after I inserted it into the holes--1 leg didn't go in completely, became further bent and touched another pin. Upon "ignition"--no flames , but smoke. Now resolved (thanks Jan), the 'lil amp impresses me daily.

I know that the Amp6 and the Amp6 Basic are a little different, but if the 6 sounds 1/2 as good as the 6 Basic (which I'm sure is not the case, it must be the other way around), then most will be impressed. I was and still am.

I just got my Amp6 working (I think). I used
Pano's stuffing sequence. Worked like a charm.
(Thanks, Pano!)

One issue I had is that it seems that one should
use a switch that is isolated from the chassis if
the mute switch is to implemented. My toggle
was not and it caused the T-amp to just click and
none of the LEDs would come on. (Must have
missed that in the instructions somewhere...)

Anyway, I measured DC offsets for both channels.
They bounce around a bit, but are in the 20-30 mV
range. I've read that some AMP6's have high
DC offsets so I guess I'm lucky.
