Default VTVM circuit for remote QRO PA monitoring

Hey OM

I guess every one knows that anything designed in the last 50 yrs is susceptible to electric surges that would be present when something terrible goes wrong, like run away parasitic oscillations, that would wipe out any solid state devices.

I haven't noticed anyone asking you why you want to build a VTVM for

this purpose. Why not use a circuit designed in the last 50 years? Is

there some inherent advantage to a VTVM in this application that a

transistorized circuit would not be able to improve on? Or is this a

nostalgia effort?
