MORE vacuum tubes, and some RF bits.
4HV members get extras, including some dual bricks I have been saving for a project..
EDIT:
Maybe useful for folks doing DLP based resin photolithography hacks? usually the lamps go on these, but the DLP rarely breaks and isn't that expensive.

Would be interested if anyone wants my non working 2 stage, its seized but goes 1/4 turn in each direction. I bought it in this state but pretty sure that it is repairable if someone has the knowledge and expertise.

Here's a tutorial for unseizing a stuck direct drive or belt driven rotary vacuum pump if you want to take a crack at it.

One of those old mercury maze puzzles is up for sale in the UK, ending on April 19.
This is the kind with a hexagonal maze. I got one for myself a month or so ago for around $25, and just won one with a round geometry for around $35. Still need the square kind - one seller has a few but is waiting for people willing to spend $60.
Who wants to collaborate on making replicas, or original designs, by 3D printing?
