So I got a great deal on a vintage Browning CB. I was all set to have it sent in and cleaned and aligned but then I found an unmolested Sears Roadtalker. One I can likely install under the dash if I move my gauges. The other...I think the transmission tunnel will support it but I'm not entirely sure.

Not sure I'd even find 1…am I stepin over any limits to ask how much something like that would cost?
Thanks, I'd understand if you'd not answer.
That Sears roadtalker is cool, both are nice. I'd recap the electrolytic capacitors in the power supply, it isn't difficult or expensive or anything like that; because they are well past their "best by" date. They are in some ways sort of like a rechargeable battery, eventually they just won't store up and hold a charge, and leak electrolyte.

The innards inside. Most everything electronic uses electrolytic capacitors as part of the main power supply. These dry up, wear out, short out, leak, or generally lose their ability to filter the rectified DC into a smooth waveform. A defective power supply can eventually roast otherwise expensive or unobtanium components, reduced performance, excessive hum etc. Anything that old, if it's expected to be put back into service, should have these replaced as part of routine service, along with general cleaning and a good alignment.
Ahhh… (-me ignorant!) thank you! what's the 'alignment' process?
Over time, over the years, various components and coils and adjustable transformers and things, their capacitance value and other things drift a little. Or a lot.
When we "tune" a radio, we are aligning it, in a way, notice how it gets scratchy and distorted on each side of the station, but nice and clear on center? The tech will get in there and tune all the transformers and coils (a whole bunch) in much the same way, for maximum output and dead on frequency.
This makes a tremendous difference in the radio's sensitivity and selectivity. Better, louder crisp audio. With FM radios for example, a good alignment makes well recorded music from an uncompressed signal downright spooky. Radios are also aligned to the specific antenna that is to be used, as the final step.
