I recently rebuild a Model H 4 minute reproducer (new diaphragm, gaskets and need). This was my first attempt to do so. On my Edison Standard, some (but not all) 4 minute blue amberol cylinders sometimes echo. It seems to be certain cylinders and not others. What would cause this problem. I thought rebuilding the reproducer would get rid of it. Is it likely a problem with the cylinders in question or the machine/reproducer? -----Original Message----- From: phono-l-bounces at oldcrank.org [mailto:phono-l-bounces at oldcrank.org] On Behalf Of phono-l-request at oldcrank.org Sent: Friday, July 07, 2006 3:00 PM To: phono-l at oldcrank.org Subject: Phono-L Digest, Vol 3, Issue 161 Send Phono-L mailing list submissions to phono-l at oldcrank.org To subscribe or unsubscribe via the World Wide Web, visit http://oldcrank.org/mailman/listinfo/phono-l or, via email, send a message with subject or body 'help' to phono-l-request at oldcrank.org You can reach the person managing the list at phono-l-owner at oldcrank.org When replying, please edit your Subject line so it is more specific than "Re: Contents of Phono-L digest..."
