Yes. There is at least one major error in the schematic for the TCM-2:

Using white-out, a ruler and a black pen, that one is easy to fix.

I wonder if there are others?

Gee...another 70 year old error...

The line on the schematic which connects the filament transformer pin 6 to the 803 filament 
pin 1 is correct. 

The line drawn from the + connection of the plate milliameter, connects to pin 7 of the 
filament transformer which is incorrect.

In addition, the line drawn from pin 5 of the 803 sockets connects to the +1350 VDC 
connection, which is incorrect.

I'll post blown-up photos on my website of the wrong connections and the corrected ones 
asap.
