well after exstensive research I have found out what brand deware I have an also found out the evac device does not connect mechanically to the dewar rather just sits on there and it is a home brew extraction device. ... so some low temp sealant and a new valve will fix my dewar on the cheap..........
drum roll please , I have scored a 35 liter for this weekend so my plans of trying to tear some 7970's this week is is game on .......
Looking forward to it and Diamond has drivers on their site now that actually work, still not paramount but workable
Now it will just be a matter of execution or epic Fail, but at least I am in conntrol of my own destany .........
