Hi Alex,

My supply is currently a "Dual Reg" by Greg Ball ...

Good, but not great. I've got a discrete shunt reg based on Salas' design almost finished too that should be better. What about you - what are you doing for a PSU?

My trannies are Jensen 4:1 step down types. The Lundahls my be OK without caps too .... perhaps you could email them to find out?
