Default Re: KB 381 5 valve AC/DC superhet

I am puzzled by a strange looking item which is not shown on the circuit or the layout drawings. It is a paxolin former, similar to what I have seen used for small coils or wire wound resistors. It connects between terminals D on L1 and B on L2, so in other words between the aerial and G4 of V1. I cant think why KB would go to the bother of fitting this if it was not to be used for anything.
Hi Mike,

As a complete guess, perhaps they are test points for easy access to G4 and the aerial circuit whilst aligning?
