Printed reproducer for old Victrola

Postby MartyS » 2019-Mar-Mon-19-Mar

Just for fun I tried designing and printing a reproducer for my Victrola, worked much better than I thought it would.

Not sure if embedding is possible here so here's a youtube link to 30 seconds of it playing a record.

That's crazy. Old tech meets new tech. Can't believe it works. Sounds pretty good too.

That's amazing! Is there a metal needle that follows the groove in the record? Did you design this yourself or find the design somewhere?

So the arm is printed as a "bridge" at the same time as the diaphragm and the rim all as one unit?
I looked at an online description of how to rebuild an original, and it had an unbelievable number of parts: mica diaphragm, gaskets, assembly screws, adjusting screws, even adjusting springs! And yours has two parts! Bravo! :geek:

Oh, and the original on my Victrola doesn't have mica, it's a metal foil diaphragm, but it does have a lot of parts, including very tiny ball bearings that fell out a few years ago as the rubber ring holding them in decayed, found a source for the bearings but it was a pain getting them in.
