Transformer is 350 mA from Thomas Mayer aka Vinylsavor
Rectifier are EY500 or 6DS22
Chokes are 4Hy 400mA from Lundahl
last LC you need double for every Speaker
R2 value is field coil winding resistance in parallel
Capacitors are ASC X386 C3 is best 2uF paper oil or much better Jensen /Bosch MP Capacitor
For fine ajustment you can swith primary winding 220V 230V 240V
