The IC is not in production for years now. It is only available on eBay for insane price. For $30-60 it is incredible and you not even know if it is genuine.
Fortunately there are circulating on the internet a few circuit what can replace it. He picked one for me, I looked around for explanation, datasheet, other notes to check if it is feasible. Corrected a few things on it based on notes and my thoughts.
My goal was simple. Didn't wanted to put a big wired in board, but something tiny, fits in the place of the original IC.
Here is the result:
It is just a bit larger than the original DIP-16 package, and substantially higher. I hope, it will fit.
Waiting for the result on the first tuner...
