[Amps] Solder in pins for fabrication of A 3CX800A7 socket

[Conrad PA5Y]

I On it's way to me from a faraway land is a PCB that is designed to be 
part of a socket for a 3CX800. It has 2.5mm clearance plated through 
holes. I need some solder in pins to make it into a working socket. I do 
not know the diameter of the 3CX800 pins, I assume that such pins must 
exist or the PCB would never have been produced in the first place. 
Could someone point me to some suitable solder in pins with a 2.5mm 
outside diameter and a hole suitable for a snug fit to the 3CX800 pins?

Failing that the diameter of the tube pins would suffice. Yes I have a 
tube in an amplifier and yes I can measure it myself but I am sure 
someone will already know the answer to this and it saves me dismantling 
it until I am really ready :-)
