Early 604 cone solution?

[Audio_by_Goodwill]

If it's the same gentleman that I'm thinking of.Dave (Dgwojo) said he went to herculean efforts to save his original cones by replacing the cloth surrounds on the original cones on a pair of 416's he had. A service you can't get everywhere.

I was thinking 515s, but he may have had both done at one point or another.

What's odd to me is there are no cone#'s on those cones.No way to trace the manufacturer.

I noticed that too.
