I'm trying to fix a TV tuner that has a bad prescaler IC.  The set isn't
very old but the IC that's in it is apparently already obsolete.  I haven't
been able to find a replacement anywhere.  I need help.

The part is a Plessey SP4020 (or Siemens SDA4020).

Plessey has another part (that is also now not available) that is a close
second: SP4634.

All of the other parts I can get won't work.   Can anyone suggest where I
can get one of these parts?
