Default PSUD2 versus Schade's Curves

In this example the receiver is a Ekco U353 which is a AC/DC job which uses a UY85 rectifier, the service info provides the figures and circuit info that's required.

PSUD2:

Reservoir capacitor ripple voltage percentage = 3.99%

RMS rectifier anode current = 0.1888 Amps

Rectifier anode supply VA = 45.31


Schades Curves:

Reservoir capacitor ripple voltage percentage = 4.2% (approx.)

RMS rectifier anode current = 0.198 Amps (approx.)

Rectifier anode supply VA = 47.52 (approx.)

Not a lot of difference.
