You use the word bypassed. I presume you completely disconnected the multiple pack replacing it with the .047uf. Nothing like enough coupling but it should have given some line scan and not damped the LOPT.

Before writing the scan coils off I would have a very close look at them. Make sure the connections are not shorting to the core or chassis due to rotten insulation or trapping.

I still feel the scan coils are OK but you never know with this old equipment. I never changed a set of KB scan coils other than the type fitted in the RV30 but this was for the poor interlace problem, never a shorted line coil. Worth having a close look. John
