Just a heads up for people wanting to order chokes.
This one is in stock.
It has a 1mm gap, so when 2 are put together it gives a 2mm gap (might be too high.... dunno)??

God knows how they didn't come broken, the packing was terrible and these things are really brittle..... I'm buying a tatts ticket tonight.

The 0.1mm, 0.2mm and 0.5mm are all discontinued.

IF you have the other type (yes, it's great to have lots of spares) like here they do match up nicely size wise, so you can use one of each to get a 1mm gap.

I also recovered some with a total of 4mm gap from some delta GTI's, they appear to be the same size.

So ransack the gti's you come across, some have good bits inside.

2 sets of the 8850's might be a good option if enough wire will fit.

BTW has anyone got one of these testers  are they as precise as a railway nail?
