IMHO your fine with the re-location of the cap mentioned with an image of a wire with red dots. That wire is or looks to be the AVC bus. That is a negative voltage at very small current that is used to control the gain of the RF/IF tubes so stations are all at the same loudness level. The cap not only bypasses local RF but its value is part of a timing circuit so the AVC acts with reasonable timing.
It is important that the AVC circuit have no losses...
Placing caps on top of a block is O.K. especially when new caps are too large to fit inside.
BTW have you decided on a vendor and ordered your OPT?
