Stand By and Slow Heater Turnon

[Strelok]

Hello all you happy people,

What's the deal with Stand By nowadays?

I read many things in Kevin's excellent books.
If "cathode stripping" is an issue than I should have those switches in all my preamps too!
Or does that only come into play with amps of "high voltage", which I learned is originally 1000V+ ?

I'm building a Jim Kelly amp like in the project, and for geographical reasons (the layout of my PS that is) I woul dlike to have that switch after the first resistor.
That should be no problem I think?

Is the strain on the switch not too much?


Also, I saw an excellent schematic for building a slow power-up for the heaters.
Is anyone doing this?
Is this schematic only meant for DC operation?
I'm asking this because I remember a BJT there.


Kind regards,

Strelok
