[Elecraft] Ameritron 240V inrush limiter: any benefit on a KPA500?

[Bob McGraw K4TAX]

"Amplifier" as in all inclusive.  The models I referenced all have 
internal power supplies, with exception of 2 models.    The design of 
the transformers in these amplifiers are such that inrush current does 
not exceed maximum magnetization current.
