[TenTec] Proper TenTec 960 power Supply Schematic

[DJ <75a4@cox.net>]

Hi All

Could some one let me know if there is a proper schematic for my TenTec 960 
power supply;y ,none I have are proper in terms of parts.

Problem is that  I turn on supply , I can Adjust to proper voltage, but when I 
put any load on the supply like 1 to 18 amps amp it, the voltage goes to zero 
volts.

Take load of it is ok with proper voltage , have two supplies with same problem.

Sure could use some help on this.

Checked all the parts ,have replaced parts , 723 on all, my brain is gone .

Thank you for the read
