Ok. Let’s try this again…RCA 9TC240 Alignment

I may not be available in the morning so here goes. The table measuring at the junction of L104 and R126 is impossible because on my diagram there is no junction.
The reason your VTVM goes off scale is because there is a DC bias of at least 10vdc there.
To adjust the traps do this:
Connect the VTVM to pin 1 of V106 and ground.
Switch the VTVM to the 5vac range. Not DC.
Next switch the HP8601a AM modulation on to 1kHz.
Adjust input RF until you see about 3 volts AC on the VTVM
Adjust the traps null at frequency specified.
Raise the RF level as necessary to keep the null at no less than 1 vac.
Repeat this for each of the trap frequencies.
