Just a few thoughts, gentlemen. Watts, I'm not qualified to answer your qs, so will leave to others. Peter is not open to batt psu, or tube psu options for his SG. This is a shame, since my batt psu is pushing the cart to new heights of greatness esp re airy highs, and transparent mids.
Re tube options, the Straingauge tech has been around for a long time, and Dave Slagle of Emia fame has a bespoke tube psu for his NOS Panasonic Straingauges, and it may be compatible for Peter's current version. Beyond this I don't know too much, but the options are out there.
