For the +36volt rail and the -36volt rail of the powersupply are for a discrete class A poweramplifyer (Blame ST). The +/-36volts is an estimate of what will happen if i drop the secondary voltage of the transformer by six volts from the original schematic (Was +/-42volts). I have no clue if this will even work. And i still need to set the values of the two resistors and capasitor in the relay circuit, which might I add, can't be done untell I know for certan what the VAC of the secondary side needs to be inorder to get the 36volts on the rails for the Blame ST.

If i drop the voltage to 24volts (from 30volts) on the primary side of transformer and stick a second 1N4007 before the rectifier(Which connects to the Voltage regulator). Then the LM7805T will only need to regulate 24volts, right? I think the Lightspeed will be pulling less then 1 amp.

I would like to create some sort of alterd schematic from the original schematic so that I can doccument the changes. Starting will removing the six 1N4007 leading to the 56volt rails.

Thanks for all your help so far!
