Tube Pin Identification
#10

Here's the difference between the Philco schematic you have posted and the pin-out diagrams in the databases:

[Image: https://dl.dropboxusercontent.com/u/5462...UBE101.jpg]

The Philco schematic is on the left and the pin connections as seen from the bottom of the tube are listed in RED numbers.  You need to look at the actual elements in the tube, i.e. the plate (pin 2), the cathode (pin 5), the grid closest to the plate (pin 4) etc.  The grid cap on the top of the tube is unnumbered.

Hope that helps.
