It will probably be okay, but I'd put coils with slightly longer distance.

Especially the one "beside" the 2,4mH in the same direction, just to avoid issue...

Question, which schematic you decided to use? the Equivalent not charged coupled that use the Coils to simulate the autotransformer?

[laszlo]

You guys are great.
precis why I put the picture up so I can get advice from you.
I rearrange the coils... and puts 2. layout up later.


The diagram is borrowed from H.B from the forum.

cheers

This is a much better solution!

Coils will not affect each others.

Ciao,
I don't see problem with last design due to distance > than 2cm.

but if you want to Avoid 100% mutual coupling, do a further improvement.

Personal suggestion: Separate the filter in "clearly visible" Cells (MF-HF-UHF) in section.
don't place the filter inside the cabinet (vibration, future modification, solderjoint failures/crack, multiamping passive etc..)

If you keep the filter outside there is no need to use Glue to fix components or many straps.

Many thanks for the comment :-)
I was inspired by Mr. Widget's external filter and used it as inspiration.
