It is indeed an interesting thread, however in my case I just felt that
there was not enough contact at all and also this particular
implementation was done on the cheap, rather badly. In fact there was
about 5 fingers at each of the fixing positions for the socket, many of
which had broken off. I felt that this was not an ideal situation and so
decided to remedy it. I mistakenly thought that the SK-1900 was in fact
a socket with a grid collet but have since found out that this is not
the case.
A picture speaks a thousand words so have a look at this:

Notice the sputter marks, apparently the blower failed and no one noticed!

In looking at an SK-2200 I have here in the shack, I see the 4 grid tabs spaced
equally around the socket.
However, the grid collet in my Henry 3002 is the real thing having finger stock
all the way around.
I have a couple of NOS screen grid bypass caps for the 4CX150/250 series tubes.
I wonder if that could somehow modified or used in this instance.
