Hi Terry,

Thanks for responding to my post.  Based on your information, I have made some progress, just no entirely the kind I want.

1)  I still have not found R14 on the schematic, although as stated it is shown on the schematics I found. 
2)  It turns out that the  shadow box coil is open, I put a 1K resistor across the two shadow box leads.  This allowed the plate voltage to go to 353 volts.
3)  The power switch coupled with the band control is not working properly.  I bypassed the power switch, but I am not sure if the band switch is working.  There is no information that I can find about this switch other than the part number.

The radio started to motorboat, which led me quickly finding a missing tube  #44 shield on.  I have the shield but no mounting socket.  One of the socket rivets was pulled through.  So I need a rube shield base and then have drill out both the 44 tube socket and the associated corner bracket in order gain access so that I can reinstall both the tube socket and shield base.  Not what I wished for.  With the tube shield held manually down, motor boating stopped but cannot receive any stations. 

I need the following components and would appreciate suggestions as to where to get them.

a)  Shadow box for the Philco 91 receiver
b)  Shield base and associated shield for #44 tube
c)  Grill cloth for the model 91 version 126 radio.

Thanks

Bruce
I hate to give up on this set as the cabinet is good and I had refinished it several years ago.  I have a model 90, which is next on my list of projects.
