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? Jerry Willard, Tektronix jerryw@teksce.SCE.TEK.COM
