Okay, I looked on eBay and found none, though there was one seller with the RX and TX crystal but may not be the wattage.
I found this site:
Quartz Crystals
And this site:
US CB Radio Channel Crystal Frequencies | The Old Tube Radio Archives
TX: 27.025 RX: 26.570
At the electronic supply website, use control + F in your browser and search for those frequencies. I
think you need the HC6-U type. If you have crystals already and a caliper measure them. The diagram is in millimeters.
Edit-
Okay, pulled out the old Realistic TRC-214 and measured a crystal with my caliper. It's an HC-25. The electronics supplier has the TX crystal in that format but the not RX crystal. That one may be on eBay. I have no idea what the wattage of these are though. You'd have to contact the electronics supplier. No idea if it makes a difference either.
Let me see if Digikey, Mouser or another electronics supplier has these.
