[TenTec] Ten-Tec 9420 Hercules power supply schematic.

[Randy Randall]

Hello all,
 
I just picked up a Ten-Tec 420 Hercules II amp this past weekend with an Astron RM-70 power supply.  Since the overload protection is in the Ten-Tec power supply I would like to see what scheme TT used.  Whoever had the amp before me did not include any overload protection not even a  lowly fuse.   I have not been able to locate the schematic from the usual sources and was hoping someone here had a copy.
 
Thanks
Randy.
