IERC tube heatsinks were very common in high end commercial / mil grade communications gear on the smaller 7 and 9 pin tubes. There were at least five sizes that I know of.

There were also other makers, but IERC are the most common and best known.

They are still seen sometimes at hamfests - they look like a matte black tube shield with internal grippers to tightly grasp the tube. Cost depends on whether or not the seller knows what they are.

They are very effective at heat dissipation.

edit: Surplus Sales of Nebraska has them for sale on their website.
