| This particular key project is a copy of the famous Marconi
P.S 213A I have seen a few copies, most are what I would call "look-a-likes"
as they seem to have quite a few variations from the original design, I have
tried to keep this one fairly close so far, the main difference being the
bearings which are 7mm ballraces but I have kept them hidden inside the
bearing support arms, and I have fitted dummy side screws to the outside,
the main difficulty has been the slotted contact spacing adjustment tighteners,
not being able to cut a slot that fine I have made a slot by cutting a
recess and then fitting a brass strip over the top which looks quite good
and works well, It does have a lovely action, I'm very pleased with it below you can see the YUH version against an
original 213 ( Original pictures by kind permission of John G0RDO) |
