The Talking Machine Forum — For All Antique Phonographs & Recordings

The rubber isolators are available in reproduction form. Search for Ron Sitko on this forum for a reasonable priced replacement. Otherwise google "Rocky mountain rubber" for an alternative replacement.

Thanks, I'll pick up a couple from Ron in Wayne next month. I did manage to get the ring off using gentle taps from a hammer. I may send the ring to Rocky Mountain; I've never tried their isolators.

Whoever worked on this Exhibition was pretty clueless. The gaskets were hard, squared-off black plastic that didn't quite meet. The screw on the diaphragm was covered in thick shellac instead of wax.

I can't wait to see how they screwed up the motor!

Replacement isolators are also available from the manufacturer at Rocky Mountain Rubber Co. The owner is John Gubbins who is also a collector. Just Google it.
