However, the circle diameter of the pins is 11/16 and the circuit board hole diameter is 1 1/8. I tried to bend the pins out 90 degrees but they snap off. Fudge.
I seem to remember Steve at angela.com saying sockets like that
were used on boards where the tubes were initially soldered
right to the board. I think in cheap guitar amps? Had anyone
ever seen that? I can't think of any applications where the
pins are 1 to 1 on Octals.

Yep, a company called AMC sold amps that the four EL34 tubes were soldered directly to the boards. Each board held a pair of '34's, the rest of the circuitry was solid state. When a tube failed, you were supposed to replace the whole module they were attached to.

All the tube resellers should carry them.
