So give me a rough sketch of how the circuit would be set up.....just a chain of diodes?

Math to determine resistor values if you want it here:https://en.wikipedia.org/wiki/LM317#Voltage_regulator The important thing to remember is that these regulators can have any input/output voltage, but the difference between input and output must not exceed 40V. So if say your input voltages changes by more than 20V above that rating you quoted during warmup you need to know how much and plan additional regs set to feed voltages lower than that peak in 40V decrements per stage. I've used these regs (both the positive and negative voltage variants) in all manner of circuit with good results. I've regulated 200V tube B+ supplies and supplies under 30V with them. I've put 3+ in parallel for high current applications, and I've put several in series where I had to drop some multiple of 40V....It would not be a stretch to say they are my favorite SS part to build/modify things with (I've been buying them by the dozen).
