The Talking Machine Forum — For All Antique Phonographs & Recordings

Dear Dave

To be frank we haven't tried tone experiments of that type, as we have focused more on recording techniques, trying to get the best out of the source cylinders themselves. We have judged our success by ear, which is not very scientific but at least matches the way in which the bulk of users of the cylinders will listen to them. I don't know if Duncan Miller of Vulcan has done this with a view to seeing what he can get out of his masters, but I will ask him when I see him next.

From a quick look with a spectrum analyser during the recording process, in preparing the source sound for Vulcan to use to drive the cutter, we haven't been able to get above 5-6KHz from good condition/little played wax cylinders, perhaps a little bit more from electrically recorded blue Amberols. It would be interesting to look at the science a little bit more - have you done any research in to this, or looked at your or other recordings on a 'scope?

Hi Keith

I'm just starting on cylinders and find it fascinating that you can record on them. You can see my latest, cylinder unrelated project here, http://www.soundhifi.com/images/Timestep-RA-78rpm.pdf

Cylinders are next ! My test gear is here http://www.soundhifi.com/test.html

Working with the Prestige 16 2/3rpm Jazz series, it intuitively feels that cylinders could go to 10Khz using modern recording techniques. The problem I see is the horn in the replay system. Maybe I'll put a transducer in the bottom, or on the reproducer stylus and see what it actually gives.

But I don't want to, or need to, re-invent the wheel if someone has already done it !

As part of the upgrading of the City of London Phonograph and Gramophone Society web-site, it is now possible to see, hear and purchase these cylinders on-line with just a click of the mouse. For more information simply go to:

I would like to take this opportunity to thank all those who have bought the cylinders and helped to make the Masters Series such a success so far.

A merry christmas and a happy new year to you all.

I'm sure you won't be dissappointed when you hear them on your Triumph Sean!
