Got one more amp finished to an initial degree.

Sound-Coated the transformer cover, moved the pair of 1uF Platinums--that amp was humming a bit because I wasn't smart enough the first time to get both caps far enough away from the AC-filament cables--and added a pair of 0.47uf Platinums to the powersupply poles supplying Vs1*.

Will get the 0.47uFs installed and the 1uFs moved in the other amp, and then they'll cook for weeks while I fool around building another equipment rack, this time with 80/20 stuff. (Can't afford the rack/s I want.)

* JIC you haven't read Ralph's note, the former V1 is now two 'N7s with sections in parallel, labeled V1a and V1b.
