Hi Ed. Transformer sec'y. is 6.3 v. CT. Full winding connected to a bi-phase rectifier (CT = 0v.) then to a 10,000 uF reservoir cap. Two wires, each about 4 inches long from that cap to the regulator circuitry, which was the traditional bird's nest! No cap. at all across the output. Voltmeters connected across reservoir cap and Vout. Dummy load for initial testing was 100 ohm R. At which point, the 2v N/L dropped to about 1.3v. A wander around with the 'scope did not reveal any signs of H.F. oscillation.
