Im looking for the tune up info on the Madison. I have googled the radio but all i get is the general info like power and modulation VRs. I need the more in depth info so i can give the old girl a real tune up throughout.

Does your radio have the 858PLL or the later MB8719 PLL chip?
Not sure on the 858 model, but think it may use the same older President Grant PCB.
The later MB8719 (PC411 board) is almost the same I believe as the Cobra148GTL (PC412) model, and Uniden Grant.

You can try CB Tricks on the web. They might have complete alignment instructions for that radio.

I tried CB tricks but to no avail. I think the Cobra 2000 is very identical to the Madison inside. Ill keep looking.
