[78-L] 3 Seconds of Nothing??

[Dave Burnham]

I was mastering a set of 78s once of the Grieg Concerto and my playback hit a locked groove. I cleaned the record on my Monks to no avail. I examined the groove under a microscope but could see no obstruction but the groove remained stubbornly locked. Finally, after much more time than I should have spent on this, it dawned on me, (light bulb over my head), that the period of rotation of the locked groove was of a 33 1/3 rpm disk, but I was mastering a 78!  The locked groove was recorded!  It was easy to repair by removing the repeated revolutions but elsewhere on the set there was a skip ahead, (once again as recorded), that couldn't be repaired. Scratch that project!

I have digitized many thousands of 78 rpm records and this is the very first time I've come across this anomaly - about the middle of the recording there is a 3 second long silence, like the recording engineer accidently flipped off the switch or something.  A close examination of the play surface shows only perfectly straight groove walls about 4 grooves wide.
