Possibly in p2p for one, not on the positive board, but I haven't looked into it because I prefer this scheme, which is anti ground loop also:

Any generic green 3mm will serve you well. That question was for SSHV1 I assume.

With that one you can arrange into +/-V any positive only raw PSUs or regulators be it chip, discrete, low voltage, high voltage, whatever. NAIM NAP 250 bolt on original was like that when I serviced one.

Can't be done with two independent transformers. Common primary, two secondaries, single transformer, two bridges.
