[Heath] Marauder un-progress

[G3OOU at aol.com]

Hi Sandy
 
Some quick on load off load measurements with a test meter will point you  
in the right direction. The PA HT supply has a minimum load of around 29mA 
due  to the presence of the VR tube feed for the PA screens which would 
provide a  minimum load during key up conditions. The HT supply apparently has a 
swinging  choke to aid in minimising the voltage variation but you should 
expect more the  valve rectifiers than with solid state rectifiers.
 
I found a marked up HX10 manual at
 _http://www.northland-drifters.net/ND-downloads/MARAUDER%20MANUAL.pdf_ 
(http://www.northland-drifters.net/ND-downloads/MARAUDER%20MANUAL.pdf)  which  
might be helpful.
