Coherent Innova 90 spares wanted

Dear colleagues,

one of our Coherent Innova 90 Ar lasers went out of order because the 
water flow transducer (flow detector) in the power supply broke. We 
still had the old plastic flow detector type in the power supply. Since 
the lasers are quite old and spares are difficult to get, I want to try 
my luck on this site.

Does anybody have an old power supply for a Coherent Innova 90, which 
he/she would be ready to give away? Or alternatively one of these flow 
detectors which is lying around in a corner of the lab or sticking in 
power supply, which is not used any more? (Preferrably the newer brass 
models, but we would be happy with anything we can get.)

We are located near Strasbourg at the French/German border and close to 
Switzerland we are ready to travel a reasonable distance to pick up a 
power supply or to pay shipping charges for the flow detector or a power 
supply.

Any help would be greatly appreciated and rewarded with a few beers at 
the next ISAC meeting.

Thank you in advance.

With best regards

Jochen
