[Amps] The Plywood Box RF Amplifier

[R L Measures]

... is for sale by the owner.  As far as I know, the only mod was  
that the tube & chimney have been changed from an 8170 to an 8171.  I  
will provide gratis technical assistance to virtually any licensed  
Amateur Radio Operator who buys it and requests such.  If interested,  
E-mail me, ring my doorbell, or telephone me for contact  
information.  I will also make recommendations for circuit  
improvements if asked.
    To power the sucker up, one needs a 3-wire electric range outlet  
fed with #4 Cu, or for <50' runs, #6 Cu will do.  For the Gnd/N wire,  
#12 Cu is enough since it carries virtually zero current.  The total  
weight is 100kg, and the height is 28".

notes
  -- I do not recommend the Plywood Box amp for apartment dwellers or  
for bicycle-mobile enthusiasts.
