Good that you found the problem in the end, bummer that it happened now. I literally only ordered two glasses from the States last week and could have easily ordered one more. Best I could find them for was $47USD. Give Zivko a call, he mentioned that he has stacks of them but they are untested. You could either try pot luck or Ken Shipley has a test bench to check them before you put them in a machine and risk and further damage anywhere.
