    I'm looking for the smallest footprint TO-3 Transistor SOCKET I can find.
    Originals were Cinch (no longer made). It's just the socket pins in a triangle shaped
    plastic housing, with mounting screw-hole in the triangle (can't take a picture of it).
    I don't have room for the transistor hold-down screw area of presently manufactured sockets.
    I bought some Keystone 4513, which is basically the same thing, WITH all the extra
    footprint of a TO-3 Package. Before I take out my hacksaw and file, I'd thought I'd ask
    if somebody knows of an equivalent SOCKET out there somewhere. I've gotta come up
    with about a dozen of these things.
    The problem is the heat sink they're mounted on, it leaves me no room for a full-sized

    Update, the Keystone sockets are pretty sturdy.
    I hacksawed and filed the housings to fit the small area I needed to mount them in.
    If anybody needs to do this in the future, the Keystone 4513 has a flat surface (they call
    it 'lead-in insulating shoulders') for the transistor mounting screws. Which is what
    I needed.
    It took some time, but it worked.
