TDA7293 amplifier alive

[Tekko]

At 8 ohms theres no prob according to datasheet, but 4 ohm was not recommended.

UPDATE:

I have now made two poweramps with these devices using two per channel for 90w in 8 ohms and 140w in 4 ohms. I tested then outdoors yesterday and they worked at the first try and sounded better than expected.

I also took the step and bought speakon connectors for the speaker outputs, mostly for looks tho as the chassis will be a 19" rack one.

I have now mounted the amps into the 19" rack chassis and only have some holes and electrical work left and then i can plug it in and try if it still works after all moving around.

There are no pics as nobody were interested.

I see that theres no longer any kind of interest in the stuff i do so therefore i have descided to stop posting anything about stuff i work with.

From now on i´ll be here mostly as a reader.

Well your post has had 1071 views, maybe not everybody reading about your project feels they need to post.
It's interesting, but I have nothing to say. I guess good job.

I want this thread and all others i have posted to be deleted by a mod/admin.

I am very interested in your amp.
Have you compared it to the more common LM3886 or LM3875?

Hello tmblack! No i just hooked it up after mounting it in the chassis. I had two LM3875´s but thats half a year ago or more so no comparison can be made.

Do paralled chips sound that much better than a single chip?

More chips in paralell gives higher damping factor, >2000 if i paralell both channels.
