[HBR] Chassis kits

[Bill Fizette]

Here we are again. My apologies, but the bells are ringing!   And again, 
nothing new about using plywood covered with a grounding metal.  A 1920s REL 
receiver on my project list used a plywood plate covered with a sheet of Cu. 
A commercial item, it worked originally so I fully expect it to work again.

73 to all,  and Happy Thanksgiving, in spite of the big snow heading our 
way.
