Murphy a252 vhf question

[Mike76]

The alignment is mostly because one of the cores in the fm part of the set was melted through to the core so I replaced it. That and for the practice of doing it. I've also replaced all of the wax capacitors throughout the set. What is actually meant by the front end, excuse my ignorance.
I did think of fitting bnc plugs, so I think I'll do that.

Thanks again for all the advice,

Mike
