Fwd: Fw: [Hallicrafters] Solid State rectifiers vs Vacuum Tuberectifiers

[Jim Brannigan]

Bob,
You beat me to it!
I love watching the crescendo build, the points and counter-points (with a 
few veiled insults), then it dies down.
I think it is the Collins reflector's turn to get into it about solid 
stating the 516F-2...There is a real fight....lock and load!!!!!
