Philco "Aligning Adapter"
#2

P.S. Tore down the adaptor, had to fix White lead anyway.  Above pins correct, PLUS these inside the adaptor:
1)  pins 3, 6 & 8 connected thru (tube to socket).
2)  3.0 Meg resistor pin 4 to 6 
3)  WORST ISSUE:  pins 1 & 8 shorted!  These are filament on the 1232/7G7 and many (most?) Loctals.  Might be of some interest (?) on a series filament rig, but the 40-145 is transformer equipped. With no fuse in the unit (only on the bench) this could have been ugly.  This "adaptor" was clearly not meant for the 40-145 or anything similar. Glad I didn't just "try it".  Never measured pins 1 to 8 before tear down.  Never thought to check that!

Anyone know how a Philco "alignment adaptor" is supposed t be wired?  I might fix it up to that, if I can. 

I think the idea was to have the tubes (two) installed in the unit, thru the adaptor, with the fancy antenna system hooked up, so you can do the RF & IF alignment that way, mostly installed in the case.
