In this case someone has been moving all 12AX7 type tubes around and forcing them in or something. Anyway pins are bent and drunken and deforming the sockets. Any tips for straightening ? A brass block with precisely engineered holes to push back all into alignment ? a metal cylinder with 9 peripheral axial channels to go inside the pinning and something to run around on the outer sides of the pins ?
