Leaky paper caps or high value resistors.

Hi,
Can anyone advise on the repair of these British 1950s geiger counters?
The one I've had for years has ceased to "click". The power supply tests
fine,
and I'm getting a decent voltage to the probe unit.
The GM tube works fine in a different unit and changing to another tube
doesn't
help.
All suggestions gratefully received.
TIA
