Default Dezifix adaptor bodge.

Having taken delivery of a Polyskop, and waiting to happen across the correct adaptors, I decided to see what I could do.
The pictures probably explain it better than I can, but briefly unscrew centre pin which leaves a short M3 stud. Attach length of wire with nut, washer and solder tag to said stud. Solder wire to centre connection of N type socket. File or grind a flat on the side of the head of two M3 cheese head screws. Bind the two screws in place with 18swg steel wire, and tighten down the nuts. Job done.
Whilst not ideal, it at least provides a workable solution and doesn't require any modification to the Dezifix connector, and can easily be undone.
Rob.

Nice interim fix, Rob,

If the top frequency of the Polyskop is not too high you may scarecely see the difference.

In the late 1970s I remember seeing and lusting after the huge Polyskop SWOB units on the shelf in Ralfe Electronics in Chapel Street (near the Marylebone Flyover) in London.

all the best
Jeremy

In the late 1970s I was still using SWOB 1 and SWOB 2 professionally......

I picked up some connectors from a chap in Germany, I decided to dismantle one to see if I could adapt it.
The plastic body was easily split off with a hefty pair of sidecutters, it's loctited on and won't unscrew.
A BNC socket was soldered to the washer, using a large iron. The centre nipple was drilled out to accept the centre pin of the BNC socket, and soldered in place.
The adaptor was assembled and finally soldered up around the seam.
Finally a cable tie was added to stop the collar falling off.
