Subject: [TenTec] Hercules II and Astron RS70 Schematic and/or Manual


I've acquired a pair of used Astron RS70's to power a Hercules II. I 
would like to find a schematic. One thing I want to know is whether 
I can strap the power transformer for 240 volts. I also need to know 
about adjustment of the output voltage.  

I also need applications advice on using them to power the Herc II. 
Should I simply connect them in parallel, or should I use one to 
drive two of the Herc II output stages and one to drive the other 
two? 

Do I need some isolation diodes? Can I increase the output of the 
Astron's to compensate for the drop in the diodes? Any other ways to 
do it?
