Hi.
I'd disagree with aligning the set firstly, if the cores and trimmers have not been tampered with, most likely you have a fault than an alignment issue. Aligning a set with leaky caps and off value resistors just mean you'll need to do it all again after replacing faulty components and that includes valves as well.
One thing to note is when replacing decoupling caps and especially in an FM front end is to use capacitors of similar size and tolerance but also to fit them as near to the original position as possible and always use the same earthing point. Failure to do this can give rise to instability, wrong tuning, low gain and other maladies.
Good luck with the set, a great performer once completed.
