Looks like a very cool power supply, impressive ripple specs!
Any info on the power supply impedance?

The SLB is designed for Class A where the max current needed is always flowing. I don’t think impedance matters as much here like regulated PSU’s for Class AB Amos that may be called upon to open a pass transistor from near zero max. However, it does have a Toshiba audio grade power BJT for the Pass element set up in a CFP topology. So basically like a high speed power amp stage. I would expect impedance to be quite low.

You are welcome! Just part of the GB routine now. It is a lot of work though.

There are more SLBs left in case anyone is interested. Great PSU for typical 25w Pass Class A amps like M2 or M2X, F3/F4/F5/F6/Aleph etc, or even USSA5, Hiraga, JLH. Certainly Alpha 20, Alpha BB, MoFo, etc.
