You can buy the spring retainer clamps (similar to the Marshall, et al.
clamps) from Antique Electronic Supply (www.tubesandmore.com) for $1.95
USD each. A pittance compared to the value of the labor needed to
manufacture a kluge in your shop, even with international 1st class
postage.

See them in the Vacuum Tube Accessories area.

For those of us on the west side of the big pond, are you talking
about shields or about mounting clips to hold the tubes in place when
