Geiger Tube Holder

Hi all, just looking some help. We need to order a new Geiger tube holder with a BNC connector, however budgets are stretched. All the ones in the catalogues are about £120. Has anybody any idea of where i could source one cheaper or even second hand?
Thanks

£120 seems a good price, we bought some at £350-ish!
 
I don't quite understand why they cost so much, glorified bulb holder really aren't they? I suppose they charge so much because you are forced to pay it if you need one , it would be difficult/ unsafe to codge something up. I wonder if you could get a PET to BNC adaptor?

Its not the connector that is the problem its the end that holds the tube thats causing us issues!

is it a right angle connection, in ours there is a solder joint inside, if you unscrew it you can check if it is unbroken.

If I remember rightly this was made back In the day , When things were easier to take apart and "repair" maybe this is a route to go down
The problem that I found with these GM tube sockets was that the tube would work loose. Using a sharp implement, it is possible to **gently** bend the contacts so as hold the tube more securely. The contact material seems quite soft and not particularly springy.

Yes, I'm always worried the tube will drop out!
