Just a thought or two.. The Riders procedure pre-dates the conventional practice of using a sweep generator and scope for alignment. Is there a Sams of this set giving sweep alignment instructions? If so, learning sweep alignment would be far more beneficial long-term than trying to do a one-off using the obsolete procedure.

If nothing was disturbed other than those two IF xfmrs., I would first try tweaking them, looking for best fine detail in the pic consistent with no ringing or smearing of detail.

If alignment is still necessary, and if sweep alignment instruction for the set is available, try to get someone with a genny and scope to mentor you. Or if you already have genny and scope, the collective wisdom here could walk you through it. (Of course the genny has to be able to do the old 24 mc. IF.)

While the old method may work OK, the scope gives you a visual graphic of exactly what the IF strip is doing.

BTW, the two things you replaced were IF transformers and not traps, right?
