Yes this is the amp .. but site is in Portuguese and google translation of users comments are not working on my end..
So asking experts on DIYAUDIO to give some comments.
I want to build this btl amp , but i don't know where to buy the ic. I found this one on ebay : 2 Pcs TDA7294 DMOS Audio Amplifier Original from St ICS | eBay
Someone has purchased from this seller? or someone can recommend some place to buy the ic and that offers free
(or cheap) international shipping to Colombia?
Thanks

Hello.
Hi this is my first message. Here are some pictures of my last TDA7294 Bridged. It was made in base to Saytronic design (user of other forum) but this one is mine. It works Well on my 2x12" + Piezo Speaker. In the component side it reads 75W RMS
. That's not true, I did it to mess with a friend of my school
. I add a 12v fan for cooling. and reinforce the thickest tracks with solder. The PCB is 90mm x 50mm in size. I use the Toner-Laminator method in bouth sides. The supply is an 24+24 VAC transformer from an old Sony sound system. Filtering caps are 3300uF/63v plus the 2200uf/50v on the main PCB. Big diodes. The design is all done in Corel Draw.
So Hi you all. Greetings from México.

Hi rakesh_sharma23,
About the use of multiple TDA7294 PCB design size is how much?
Hello guys, I seek answer to a small question.
My question is, i have two tda7294 and two tda7293 in m drawer. i would like to bridge them. what will be the best way to bridge, for each channel, can i use one tda7294 and one tda7293 to maintain symmetry?
or should i use a pair of each on one of the boards at a time?(might create sonic differences)

much better used the same i.c.. =) number, although they are the same pin configuration..=)
do you mind if i ask where you found the sockets for the chip?
THANK YOU MR MILE GIVE ME A LOT OF SCIENCE.
GREETINGS TO ALL
1.BA200 TDA 7294 (STEREO / BRIDGE) VERSION.1
Thanks Mr Mile.
