Re: Decca

Using the original coils the inductance when measured in the case and out of the case varies by several Uh and therefore difficult to resonate/align properly


Not really.
The coils have about 3 turns at the top of the former that are not fixed other than with a tywrap.
These turns can be fully or partially wound in-phase or out of phase in order to precisely resonate the tank circuits where you need them.
