Default Re: 6 metre 4 pole filter

Try this.
We mourn their passing along with 10K, MC108 etc.
I have the similar info for those parts.

They were 1.5 turns to max 8.5 turns (= max capacity of former) with 3 different slugs, 2 types of ferrite and aluminium.

Winding OD is 7.5mm, wire dia 0.66mm, slug OD 4.5mm (could be M4.5 x0.75 thread? - unconfirmed)
Former material appears to be some form of polythene.

The colour of the former followed the resistor colour code. Green 5.5T Violet 7.5T White 8.5T etc from examples I have here also confirmed in the pdf.
