[sdiy] filter cap needed?

H^) harry,

Can I ask, oh I just did ;) Well, You and Your twin-brother separated
at birth are well known advertisers of the capacitor industry..

What is this controlled impedance and snubber business, anyhow?

Is there some Rule of Thumb frequency to be handled by the circuit,
when rails needs to be analyzed as transmission lines rather than
ideal power?
