I have a very large assortment of factory Motorola service literature. I'm pretty sure I have TS-912 info. Do you have a model/serial# on that set?

The only one I saw and worked on, didn't have UHF. If you look at the picture, it looks like a UHF kit was installed.
The horizontal output tubes, two in parallel are strange types, 12GC6 only used in Motorola sets. IIRC, the schematic also shows 12DQ6, used in some models. Different pin-out. It also has two 19AU4's.
They must've used that set as a prototype for the newer TS914, as the LE8 color demod circuit is used. The 914 used a power transformer and 6 volt variants of some of the tubes.
