Barry. 

The board comes with the torrids in the kit. You need to supply the wire for 
them. The board uses either 12 volts or 5 volts DC for the relays... I don't 
remember which. I used the voltage from my T/R relay power supply with a series 
dropping resistor. For caps, I use ARCO variable caps that can be purchased 
from RF Parts. See my pictures at:

 of the ARCO caps. 

This setup works very well. Paul, WD7S does a good job on his stuff.

When I used my LDG, I also had about 12" of cable between the tuner output and 
the cathode. I just did not like the way it worked.  

My opinion... Take the time to build and install the WD7S board. You will be 
happier with it.
