[GreenKeys] X Marks the Spot

Hi out there in TDA land!

You might remember awhile back I have been looking for a Stelma model TDA-1 manual, I do have the model TDA-2 manual, and as you might guess it's similar, but not the same, though I have it working now, after allot of tracing wires and comparing it to the print of the TDA-2, and came up with a couple of broken wires, one was cut not sure why though and replaced a couple of tubes.
My question for today is I am wanting to do the balance alignment and Gate Adjustments, the manual says to hook the oscilloscope to the test point "X" (see Figure 23) and since I don't have a manual for the TD-1 I'm not sure where to hook it to, I'm thinking to the plate of V6 some where.  Any help would be greatly appreciated.
