PCB Design help

[Angel-Baby]

Hello to everyone
I was wondering if anyone is able to help me in designing a PCB for a chip amp I salvaged from a old stereo.
The amp chip is a STK405-070 40watt per channel.
The datasheet can be downloaded from here

If anyone is able to help I would be greatly appreciated I have tried a few times at a pcb design but failed.
Thankyou
Regards

You haven't thought of using a brand new LM3875 or LM3886? Have you checked BrianGT excellent looking PCB?

Hi Peranders thanks for your reply I already have made 2 LM3875 Amps just that this STK405-070 was sitting in and old sterio that only the radio side of things works just thought I would make it into another stereo amp.

The cost of paying someone to design a PCB for you far exceeds the cost of just buying another chip and the PCB. Even at my special hobbyist rate, it would cost about $200.00 for the artwork. OK if you want a bunch to sell to others but far too much for a one off job.


As well the STKs of that generation are not all that good a sound quality anyway.

You'd be better off to salvage the PCB out of the old product and cut it down to size keeping the part you want.
