How did people at the bottom of the social pyramid support those at the top?
Well, look at the pyramid. There are more at the bottom... a lot more less powerful that hat to contribute and pay all to the owners of the land and we're allowed only to survive. In some cases, not even survive, slaves would be worked to ***** in many cases, in some civilizations under the farmers and artisans were thousands more slaves making the bottom of that pyramid wider, allowing for even more riches at the top.

Hello,
I'm not sure what you mean by 'wide open voltage'. If it's over 17v, the supply may have multiple problems. I don't have the 52kx schematic but other Pyramid supplies have over-voltage protection. There is an SCR that is triggered when the voltage gets to ~17v. This should clamp the output and trigger a shutdown. You should check the 16v Zener diode and the SCR. If the SCR or the Zener is defective, that would prevent the over-voltage from clamping the voltage. Also confirm that the SCR has a solid connection to the ground terminal of the supply. If it's open, that could prevent the clamp from shutting down the supply.
If the voltage is going high, measure the DC voltage from pin 4 to pin 5 of the LM723. It should remain the same at all times. Also measure the voltage from pin 5 to the ground terminal of the supply. That should also remain constant at all times.
How to connect my stereo reciever to my Pyramid PR 2700 mixer
Running mixer to receiver??? does the mixer have rca (red & white) audio outputs? if so you can run it that way and hookup to whatever input you want on back of stereo. If it doesn't then you can buy a 1/8" stereo jack to rca and run out of headphone out. (will need a 1/4" headphone adapter though).
