What did I get myself into?

Brian, connect a few feet of insulated wire, maybe 20 feet or so. Run it along the baseboard or drape it across the curtain rod and see what you get. The ground is not really necessary. You should be able to get your local stations. At night you may even pick up some pretty distant stations.  If you have access to your attic, You can run a wire from one end of the house to the other and drop the lead in down through a closet.

I like the attic idea.  Winter may be when I do that.  Its 94 degrees already and I'm in the mountains...Probably will still ground the unit though.  My CB radio transmits and receive farther and better with a ground plane.

The line capacitors provide a ground path for the antenna circuit. You can try the radio with and without a ground, I don't think you will be able to tell any difference.

The "directionals" are on your electrolytic condensers. These are polarity sensitive, and will not work if installed backwards, in fact they may heat up and explode! The arrow with the "-" sign points to the negative direction and should be connected to the negative side of the circuit. In a few instances, this may actually be a less positive place in the circuit, so study the schematic and the existing connections carefully.

Thanks for the reply and advice.  It comes right on time as I plan on doing the swap tomorrow if time allows.
