With a LCLC filter if add some capacitance before L1 that will bump up the B+. I am pretty sure that adding 5uf will give me an additional 30 to 50 volts. I am going to take the ps to the shop today and put the additional capacitor in the circuit and see what i get. cheers

But if adding more first C increases your B+, that tells me there was not enough first C to begin with. I know it's a common trick to adjust the B+ by varying the first C but I don't personally like that approach.
He means going from a LCLC filter to a cLCLC filter.

I don't see how that would be a significant difference being either too low or too high.
model it both ways in PSUD. Remember that a CLC is going to differ in terms of what it can deliver vs. an LC supply. (higher B+, lower current)
