Actually, in SE amp (1) I slowly build (long breadbording phase), I use toroidal PTs (2), "ordinary" 5V4G rectifiers (3) CLC filter (4) with MKP first cap, but electrolitic second (5), actually, 2x270uF (6), 130 Ohms 10H choke (7), even add 10 Ohms resistors between the secondary and the rectifier (8), maybe I`ll bypass electrolitics with MKP closer to the 300B (9)... Huh, I really tried, but can`t do 10 Mortal Sins in Audio...sorry. In my defense, I use small 35VA transformer for the heater (6,3V) and filaments (2 x 5V) and separate 300VA transformer with HV 2X360V + 2 x 5V for the rectifiers. Few swithes, and I have standby function like this: main switch on - small trafo is "on" through power resistor (~0,8 Uh on the load), then standby switch "on", and both transformers are "on" - IDH rectifiers provide ~30 sec. more "slow start". In standby, HV is "off" and heaters/filaments are heated with 0,8Uh...
