[Central-Electronics] Info needed on mercury batteries in the CE-200V

[K6JEK]

Yes.   It is a common modification to replace the batteries with anti  
parallel Zeners or strings of regular diodes.   This is described in  
some Electric Radio articles and elsewhere.  The batteries tend to  
leak and make a mess of the chassis.  The diodes work fine.
