Philco model 50-1483

[Microtrol]

Hi all,
I picked up a philco 12 inch console set with chassis model 50-1483. I picked up the photofact for the 1476-1482 family and this unit is close but has many new components such as 2 1b3 tubes for the high voltage section as to the one that the 1476 models have. I've searched the web for this model as well as SAMs and have not found the schematics for this model. Anyone know of where I can find em or is there another family that this unit belongs too, thanks,
Brandt
