[Hallicrafters] Solid state rectifier and matching 6V6s

[jeremy-ca]

Variacs can be pricy especially when you have radios in several rooms. A 
cheaper alternative is to get a 250' coil of #18 or #20 zip cord and let 
Isquared R do the work. Getting the input down around 105-108V does wonders 
for heat reduction.
