[Hammarlund] HX-50 snapping noise

[Bill Cromwell]

Hi Bob,

Where is C162C connected. The schematic I have shows only A and B. 
Obviously I'm overlooking the 'C' unit. It may be used in some other 
part of the circuit than the A and B units which are shown as part of a 
power supply filter. If I have a clue about where to look it will help.

I have looked at some of the schematics for newer solid state rigs - 
mostly the mom n pop kit ones and the parts numbering systems are not 
systems at all with the bits scattered all over. Takes forever to find 
them even "with" part numbers. No wonder those kit builders got into 
trouble. Your HX-50 may have some parts that are in a different 
"version" than the one for the schematic om BAMA. I'll see if there is 
one for a "B" model or some other such.

73,

Bill  KU8H
