Has anyone done the HiFi/wideband audio caps on a new RCI 29 base yet? If so, where can I get the directions / board locations please Thanks - Bob

Is there any schematic?

Why would anyone use hifi caps in a CB radio, with a maximum of 2.4khz audio bandwidth? As long as the caps are reliable and can handle the voltage it will be perfectly fine. Good caps in the power supply of course.

What he's talking about is changing the values of certain capacitors in the audio chain to widen the response.

You could try wwdpx for the goldfinger hifi mods. Not sure of the board in the 29 base but it has to be similar to most any Ranger board out there. You could possibly find one there for reference to yours.

Just a thought.
