you can leave the other IF tubes in, and remove the 3rd, as it could interfere with the input.
As for AGC, the set has a combo tube, AGC SYNC SEP, , the latter being needed for video lock.
so all that's needed to be pulled is V3, the rest can stay, they will just have nothing to do with no input if they are in the RF/IF stages.
