[Amps] WD7S Input board

[Jim W7RY]

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: http://s900.photobucket.com/albums/ac206/w7ry/3CX800%20Amplifier/?action=view&current=DSC_0015.jpg  

and http://s900.photobucket.com/albums/ac206/w7ry/3CX800%20Amplifier/?action=view&current=DSC_0012.jpg 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.
