Yes you can make one out of an old neck board from a tv set. This is provided that the set has a tube number that crosses to a CR23 adapter. This way you can be assured the socket will physically fit tubes matching a CR23 cross reference.
You can unsolder the socket from the neck board and simply solder new wires to the correct pin numbers. Be sure to slide some heat shrink tubing over the connection to help prevent the delicate pins from breaking off when you use the adapter. You can also just run a bead of clear silicone glue around the soldered connections which will also beef up the delicate pins after the glue has dried.
Many neckboards already have the pin numbers and function silkscreened right on the board to make it easy to identify. You can unsolder all the parts off of the neck board and then the board can have the new wires soldered directly to the socket terminals on the foil side. There's usually a hole near the edge of the board where you can wire tie the wires for a strain relief.
See my pictures for details.
Also, to help in wiring up the adapter, visit these two links:

By the way, the one shown in the pictures is one I just made and have tested. It works perfectly and is for sale. I already have a factory CR23 I use all the time.
