Actually, I've got a very detailed C-21 manual that has a separate page 
for each and every module, including description, schematic, and photo.

However, on the final amplifier page it shows the adjustment pot, but 
gives no instructions on how or where to measure the current.  The only 
things accessible on the final amp are the input and output connectors, 
and three soldered on connections.

I'm leaning toward "T" (the switched transmit voltage.  The other two 
are 12 volt positive to the finals and drivers.
