[R-390] line voltage reducing question

[wli]

Agree with Bob. An in-line choke would introduce unintended consequences as he has outlined. For my collection, I use a 5A metered Variac. By having a transformer-type line coniditioner, and a computer-type AC switch selector, each of my three receivers can be easily powered up individually. Furthermore, the Variac is isolated from the shack's AC line.

A bucking transformer has one big advantage other than cost... it can be mounted inside the R390A, obviating another external *box*.
