diodes

[Gerald C. Lemay]

Using bypass capacitors and resistors across diode strings is no-longer valid. That
method was used when diode characteristics varied widely from lot to lot. So, forget the
resistors. The capacitors, it was found, actually increase the likelyhood of transient
noise and spikes of damaging or burning out diodes. Modern components have changed the
rules.
