Glad this question has come up as looking for some for Tri Zone and wondered if readily available or otherwise, having found somewhat bewildering choice of similar connectors when previously looking on CPC/Farnell/RS etc.
Seems 8-ways (No. 09-48-2086) are in stock £1.01each for 10+ but there is a £12.00 delivery charge for orders under £33 - anyone interested in chipping in ...
33 could be bought for £33.33 delivered - should then be possible to send on for 2nd class Large Letter rate (88p/package)
mouser want 40 quid for 33 of the headers delivered,that's an expensive replacement!,I read somewhere(can't find it now),that someone on pinside inserted connector pins from the top of the board once it was connected into the existing housings,so I may give that a go first
