Default Digital TV

Not quite audio but close(?).
Do anyone know where could I buy a turner pack (those closed shiny ones inside) for digital tv set top box. They seems to be very weak parts, and I was thinking to get them as spares. So far I found only stock sellers.

RF part in closed tin box, in every RF reciever on transistor age. Part where antenna usually is connected.

That is the VHF/UHF tuner. Unless you get lots of electrical storms unlikely to be unreliable. The tuner may be a generic off-the-shelf item, or sometimes specially designed for the particular unit.

The PSU (and other electrolytic caps) is usually the STB weak point.

The tuner for a STB is just as likely to be all SMD (surface mount) on the main PCB even though it does have screening cans around and over it.

Make and model maybe

And messing about with rf designs is not always reccomended, very touchy.
