[AMRadio] 807's triode connection question...

[ka1iic at prexar.com]

Hi guys me again,

I've been looking up all the info I can get about using 807's in triode
connection....

I have found 3 different cases and was wondering about the benefits of
each....

First off the older ARRL handbooks show connecting the grid to the screen
through a 20k ohm resistor and driving the screen...

Another publication shows connecting the screen to the plate directly and
driving the grid as you normally would...

And case three shows connecting the screen to the plate through a 100 ohm
resistor and driving the grid as per the norm...

Any guidance is welcome...  any comments welcome also...

Thanks in advance
