this one is a well known page. The problem of finding a MC1377 still remain.
I didn't known about NTE879. I downloaded the datasheet, but there is no example on it. It seems to need a delay line as well (not easy to find neither). I will have a look at that one later, thanks.

is a pay page. I don't want to spend money to guet a datasheet I am not sure to use.

That is a better one. But I already knew Analog Devices and Philips products. AD723, AD724 are not cheap, and most of TDAs are for numeric signals concerning video signals. Those for analog signals can't be found in france neither.
So a little hope would be that NTE879 could match some example of other datasheets product I already downloaded (quartz frequency, capacitor values, etc) and if either it doesn't need delay line componants or I could find a cheap one.
I already thought about finding a video camcorder or a VCR out of order to pick up some componants on it free, but I haven't met somebody who wants to get rid of a breaked one yet. Still hoping...
