Default Re: Philips N4520 alignment problems

I've had another go at re-aligning the heads but the results are very similar, there's still crosstalk present.

I've attached pictures of the record and playback heads with and without the tape present as currently set up for minimum crosstalk. I'm confused as to exactly which part of the head is the active part as they don't look like any tape head I've seen before. Can anyone point me in the right direction as to where the active part is?

The service manual states the active part of the head should be just below the edge of the tape but if I set it up where I think the active part is the crosstalk is much worse.

The heads are supposed to be "long life" which I assume they don't wear as quickly as "normal life" heads but the deck is around 40 years old and I don't know how much use it's had. Is it possible that a worn head could cause the crosstalk problem?
