Bill - that's good to know about the 2 valves.

Paul - Can you give me any more info on the valves you are getting from the states? What valves are they? When do you expect to know if they are definitely coming? and how much do you expect them to cost?

I've been generously offered a free sample valve from Clippard - it's the 'MNV-1K' though as that's the closest to the 4k2 they have in stock. Do you think this would be of any use?

I've tried to compare it to the MNV-4K2 but have no idea what the specs mean ...
