[Hallicrafters] HP signal generator modification

[Waldo Magnuson]

   Hey Carl, awhile back I think you mentioned you had modified a HP signal general so there would be a high level output to run a frequency counter when doing alignments.
   I have a HP606A and would like to be able to read the frequency with the RF turned down.  I understand the HP-606B has such an output.  
   If you have the 606B schematic on where the output is taken from I would appreciate a copy of the schematic or a description on how you did it.  Thanks.
