You could use the LME49811 instead. It is similar to the TDA7250. The datasheet from National Semiconductor has a PCB layout.
Hi
I have all the components for the TDA7250 amplifier with output transistors 2SC5200/2SA1943!
Otherwise, this circuit is much LME49811 expensive and difficult to be located?
thanks

You can get the datasheet for the LME49811 here:
LME49811 - High Fidelity 200 Volt Power Amplifier Input Stage with Shutdown
In my part of the world the LME49811 is available as a special order, for delivery within a week, for about US$10. It should work with 2SC5200/2SA1943 output transistors.

Hi Jaycee!
Neither can we understand ... I need the TOP PCB layuout (See picture above!)!
Regards!

Here is the web page.
You will need different transisors for their board. The circuit is a little different from yours.
You will have to ask them about the price for the PCB as it is not listed.![]()
As opposed to discrete designs, the IA502 uses an IC to drive the power stages.![]()
The entire power amplifier circuitry for 2-channels are squeezed into a tiny TDA7250 10-pin IC. All that's required are four power darlingtons and some passive components to complete a high performance stereo amplifier. No biasing is required as the IC auto biases the output transistors.
The IA502 lends itself well to multi-channel amplification.
A 6~8 channel power amplifier can easily be constructed even by beginners.

Thanks Ingenieus!
I need PCB (Figure not Picture) for stereo amplifier with TDA7250 with output transistors 2SC5200/2SA1943, not Darligton transistors!🙁
(See schematic above)
