    ::What happens is -- and this can happen even on Eimac sockets -- hundreds of thermal cycles work harden the socket contacts so they become stiff and brittle and eventually might lose good contact with the tube pins.

    Thankfully, not much of a big deal. Even if you have to replace an Ameritron socket, they'll sell you a new one for $20 and it takes five minutes to replace (other than removing all the damned screws in the cover!):mad:
