It's the PS for a fairly esoteric moving coil pickup pre-amp which uses
balanced inputs. The quiescent current at least is very similar on each
rail. Basically was chasing the last residue of hum, and discovered (by
accident) if I disconnected the transformer centre tap it improved. The
scope showed the hum to be more on the negative rail. Changing the neg reg
to a different make improved things to the point I doubt I'll better.
