The new octal power tube socket and PCB kit might help you out in your next project. The board is small, 2 by 2 inch, that has been designed to hold a single tube socket and a few resistors. Many like to see tubes protrude from the chassis top panel, like missiles leaving their silos. These boards help make that possible. Each PCB comes with a ceramic tube socket and four sets of aluminum hex standoffs (0.75in) and rubber O-rings and screws. The PCB materiel is thick (0.93in) and tough (2 oz copper traces), so there is no chance that it will bend, as the tube is pulled from or pushed into its socket.
Designed to work with 6L6, EL34, 6500, KT66, KT77, and KT88... Kits include PCB, eight rubber O-rings, eight screws, one ceramic tube socket, one Heyco black-plastic 2 inch hole snap bushing, which converts raw-edged holes to smooth, neat holes.
