Modeling the Bugle 45 PSU, any comments?




I have been trying to learn PSUD 2 and model the stock PSU for the Bugle 45 SET amp as a starting point, and produced the attached model for one channel. Each channel has a 30H choke, followed by two 100uF caps and a 20uF cap. I didn't know a better way to model the one-channel LC-CC filter other than turning the last two caps (100uF and 20uF) into a RC having a very small R (LC-RCRC), since PSUD did not allow inserting the last two caps alone. Originally I had used 10mOhms for R1 and R2, but ripple was 69mV, and the Bugle is supposed to have 30mV of ripple maximum. So the values for R1 and R2 were increased to 40ohms until a ripple value of 30mV was attained at 10msecs after a delay of 20 seconds. Is this a satisfactory model, or is there a better way to model the stock PSU for this amp to produce 30mVripple?
