Assembling the RX2 backplane and control boards..

Our adventure continues with the "back plane" and control board assembly and mounting. Just to let you know, though, that the quality of the project box Lou provides -- like his other components -- is superior. It's a plastic box with countersunk lid holes and even screw covers. The only difficulty I found (and I am leaping ahead here) was that the box screws were self-tapping and tough to unscrew for subsequent noise bridge re-adjustment and battery changing. With the threat of stripping the screw heads imminent, I cast about the junk box for more substantial Phillips head machine screws that fit nicely and were more easily removed. Here is a sample with a screw cap:

Assembling the back plane and control boards involve the controls (variable cap and pot) and coax socket hardware. With the pictures and instructions and videos provided by Lou, the process is moderately plain sailing.
