Hi Al,
I have been playing around with a similar design In LTspice. The main reason I gave up on it is that I struggled to find a PNP transistor with a high enough VCE for the constant current source.
One advantage(I think) is that the current limiter design on mine is slightly different. Mine would allow the current limit to be reduced to a few mA. It could be worth consideration for your design especially as it would be useful for capacitor reforming.
Alas I cannot post it here as the file is in .asc format. PM me an email address if you want to see this circuit.
