[Amps] Power transformer for 600 watt rig

[jeremy-ca]

The discussion has always assumed some capacitance to provide ripple 
filtering and some additional voltage regulation.

In a perfect world as usually seen in models, the C can go to infinity and 
there is always an improvement on the way up.

In the real world it usually depends on what level of ripple is acceptable. 
A SSB amp is less critical of ripple than an AM modulator. The voltage 
regulation benefit of more C is limited by the various suppy resistances and 
in my experience is reached at around 16-20 uF with a modern transformer.
