Just for those who are still in doubt,

Clockwise from the Bottom of the Socket:

1 Filament

2. Screen, G2

3. Control Grid, G1

4. Cathode

5 Filament

Hint: the Control Grid pin has larger space to the adjacent pins on the right and on the left of it.

For those who still do not know where pin 1 is, insert the 807 in the unwired socket.
Connect an Ohmmeter to 2 adjacent pins. Keep checking from pin to adjacent pin. There will only be one set of 2 pins that will have a reading on the Ohmmeter, pins 1 and 5.

Have fun 807 -ing.
