Triple J,
I realize this post is very old, but I was hoping you would email me a copy of the manual as well. I recently acquired a Maverick 250 and so far it seems to operate as it should. It would be nice to have the operating manual though. 73s to you. 318 in Central Ga. Email: jmarphil@duck.com
I doubt that Tripple J will see your request, he has not been here for almost 10 years.
Maybe another user can help.
The schematic is still available on CB Tricks . org
I searched years ago and found nothing.

The Maverick was made in more than one version over the years.
Here are pics of three of them:
https://cbtricks.org/Amp/d_and_a/maverick_250/
They're similar but not identical. Can't remember ever seeing instructions for that model. Exact tuning instructions would be a little different for each of the three in the pics above.
Resist the urge to use a modern radio with two final transistors or with more than about 20 Watts modulated peak output. The Maverick was designed in an era when A CB would bust a gut to deliver a 3 Watt carrier and 12 or 14 Watt AM modulation peaks. Newer radios are bigger, and will push the Maverick harder than it's built for.
Typical rule is to chose low or high side, key the radio and set the Load control for best power with audio modulation. The Tune knob will show a sharper wattmeter peak with a carrier alone, no modulation. Even the markings on the tuning knobs will be different from one year's production to the next. If your has the band selector (40-20-15) knob, turn it to 15. There will usually be age issues with equipment that's between 45 and 50 or more years old. If the mileage is really low it may function okay for a while in spite of its age.
At some point the electrolytic filter capacitors will break down. They're not meant to last 20 or 30 years, let alone nearly 50. Common practice to achieve any reliability is to replace them all. And if someone has already caught up the last 4 or 5 decades' upkeep, it may be good to go. If not, resist the urge to replace a tripped fuse with one that has a larger rating. Doing that tends to make problems worse.
