[Milsurplus] LM-10 wiring question

[john p hutchins]

Group -
I have purchased an LM-10 which the previous owner re-routed to use 6.3V 
filament.  Did a nice job.  I cannot find where he and retied the 
filament string between V101 to V102.  Pin 6 of v101 is tied to Pin 7 
v102 and the center of filament link. 
  One wire tied to socket pin 6 of V101 (HOT) Runs to (Center Filament 
Link pin).
  One wire tied to socket pin 1 of V101 ( Ground) runs who know where to 
Chassis ground?
  One Wire tied to socket Pin 1 of V102 (Ground) runs who know whereto 
Chassis ground?
  One Wire tied to socket Pin 7 of V102 (HOT) Runs to (Center Filament 
Link pin).
  Center Filament Link pin (kooks to have three wires). Uncertain if  
this is where the MOD was performed?

So does any one have a "conversion" manual that my describe where and 
how to re-wire the filament string with a minimum of effort?

Thanks
Hutch
