I dont think so, essentially because I don't know of any other compatible 3 inch CRTs out there.
Now .......... THIS SUNDAY .....!!!!! there is going to be a public auction in Chester, New York
where there will be (2) 3" CRT's offered in a lot. Not terribly far from you!
I'd take a shot and go for it if you have the time. I think the auction starts around 9AM or so...
