Ah! I didn't know that. Seems that your arm/turntable will provide a more than acceptable operating environment for the Decca. Will send it on to you shortly.
You do realise that you have now laid yourself open to writing a report on what you hear (in your system)? In fact, I'm not sure if I'm going to report the set-up details for my Decca, until you have promised to report your findings!
