Hello friends and Holiday greetings to all,

I have a request for an Opera Diaphragm. Having no cylinder machines I can't really say what size it is till I see one or if the ones I do make for the Amberola and Diamond A & B might fit it?

thanks
Larry

The Opera usually uses a Diamond A reproducer, but could also use an L or M. As far as I know, the diaphragm size is the same on all of those.

Yes. The diaphragms are the same for all of the diamond cylinder reproducers. I recently swapped one from a diamond B into a diamond A with no issues. Same for diamond B and C. They are all identical. If it turns out that the reproducer in question is an L or M, the person will need a copper diaphragm which is available from Ron Sitko.

Thanks for the replies that helps a lot. I will have to see about the model numbers to be sure.
